Saving S Files in Activity Editor

Sorry, Its me again

I have Windows 7 Home Premium, I have installed the activity RS Flying Scotsman in my EB East Coast express Route.
However I can not get it to run because SRV file RS Up_NSE 317 Woodgreen s file is out of date and needs to be saved in the activity editor.

Please can someone take me through the procedure for doing this as I cannot make head or tail of what to do.

Many thanks

Andy

Hi Andy,
I think you've already had the definitive answer to your post on UKTS

The one thing crossed my mind was that, these days, some users are having problems running the MSTS Editors. That answer doesn't help those users!! I don't have a solution for them, but if you are one, please come back.
I think the problem is caused by a discrepancy in the serial numbers shown on the various files which make up the activity, but can't be certain. The next time it happens to me, I'll do some investigating

Cheers,
Ged
