My 1MSTS has stopped working.

Hi Andy,
As Danny has said, if big routes like MEP run OK, then there's not much wrong.

Although it should run automatically, I suggest you run mprofile.exe - it's in your 1MSTS folder. You won't see much, just a short flash of a box on the screen. Then try to rerun MSTS.

Hi Andy,
Have you installed drivers for your graphics card? - the latest suitable for the 9400GT is 341.44

Have you seen this? https://support.microsoft.com/en-us/kb/299690

Also, here : http://forums.uktrainsim.com/viewtopic.php?f=273&t=126379&start=15&st=0&sk=t&sd=a

or even here, the other Andy had the same message : https://tsforum.forumotion.net/t780-midhants-railway-watercressline-route#10705

You're not using a "Virtual Machine" are you? - that seems to be the cause of the problem in those last two links.

Hi Andy,
The first link, to the Microsoft site, is your best starting point.

Just follow the instructions 1, 2, 3 & 4 and see if you get any improvement.
If not, I suggest a re-installation would probably be best, but you don't have to lose whatever is already in 1MSTS - please come back.

Hi Andy,
You don't need to access MSTS or the Editors & Tools to do what is suggested on the Microsoft webpage!
It just plain Windows, from the Start button!

.... and I don't understand why you've removed MEP as it was working OK!!

HI Mark,
Thanks for the explanation
I would never select those options! If I did, I might have a nice clean, fast PC, but I wouldn't be able to do anything!!

Hi Andy,
The Start button in in the extreme bottom left corner of your Desktop.  If your Taskbar is hidden, move the cursor to the bottom of the screen to bring it into view.

No, you've got the wrong Microsoft page!  The one I linked to shows this :

Some of the issues below can be resolved with updated drivers or by upgrading your hardware. After updating or upgrading it is important that you use the Train Simulator Troubleshooter to reprofile your new hardware and drivers. To do this follow the steps below:
Click Start, point to Programs, point to Microsoft Games, point to Train Simulator, and then click Train Simulator Troubleshooter.
Click Change Video Driver.
Click OK.
Click Play Train Simulator.

Just follow from "Click Start", don't worry about the bit before it.

From what you've reported, ie MEP was working OK, I doubt if your PC needs to be taken to the repair shop.  However, if you do and you want them to re-install MSTS, emphasise that it MUST NOT be installed into C:\Program Files or C:\Program Files (x86)!!

Ged

Hi Andy,
Don't worry about the Microsoft site, because I quoted the relevant parts in my last post.
Also, don't worry about the other links because they refer to the use of a Virtual Machine, which you know nothing about.

You can obviously use other programs OK because you are posting here. What, exactly, are you doing when the graphics card message appears?

It doesn't make sense that you can't use the Start button!

Just before it started to go wrong, had you installed anything new? If so, what was it?

It might be worth checking if you've got a recent System Restore. Systems are very often set up to take dumps whenever anything system-wise is installed, like Windows Update. If you are lucky, you might have one; if you don't know how to check :
1. Click the Start button
2. Right click on Computer (in right hand panel)
3. Left click on Properties
4. Left click on System Protection (top left of display)
5. Left click on the System Restore button
6. The next screen will show the latest System Restore, if there is one, with "Recommended restore" selected. If it is today, ignore it, because your problems started yesterday or before (didn't they?).
7. Left click on "Choose another restore point", then click on the "Next" button.
8. If there are any more System Restores, they will be displayed.
9. If you've got one a couple of days old, left click on it to highlight it, then click on the "Next" button.
10. There's one more press to go, but before you do, save any files you're working on, then click on the "Finish" button. Let Windows do the necessary and don't switch off until you get the confirmation that the Restore is complete.

Hi Andy,
Well, I've never seen that "side by side" error message before! I still think it's some software on your PC which is causing it, but have no idea what it can be - I wonder if Andy Cook, being a professional, is able to contribute anything?

Cheers,
