Hi all,
This issue is, as far as I know, caused when the checksum files of the Career scenario no longer match the change dates or filesizes (or whatever) of the scenario files and probably also those of the used rolling stock (installing physics mods tends to break Career scenarios too).
There is, I think, an easier way to fix this issue that commonly comes up after editing anything in/around career scenarios: Open the scenario in the editor, go to Timetable view. Find the Script button in the upper right corner of the screen (second or third from the right), click it. It brings up a pop-up window, on it is a button "rebuild checkums" which you should click. And you're done, you don't even need to save the scenario (no changes to the scenario itself will have been made by pressing this button anyway, only the checksums will have been updated).
Cheers
Michael
