New win10 error (?)

[Skizzy]

Ok so I admit that I haven't been playing RTW:XGM (or any RTW for that matter) in the past month or so..
Yet now, when I tried to start up the modded game through Steam (using the alternate launch options: "-ne -show_err -nm -mod:xgm", which worked fine before) it gives me this error message:



In the words of George Lucas or w/e:
"Please DimeBagHo, you're our only hope!"


EDIT: I would hate to reinstall the mod completely because I would hate to lose my saved games.. but if you think I should try that first, let me know..
The reason I wouldn't like to re-install is because I am unsure of the certain choices I made months ago when installing this mod.. and every deviation from those original choices could corrupt my savegames...
