Yes I've had it. It seems i have to verify the files now and then, mostly after the minor updates coming now. I have an old computer, so I'm not too surprised. After trying a mod with automatic announcements, it went bananas. I uninstalled an reinstalled (Steam) it runs well so far. I thought the mod was gone, but the trains are still talking. If it don't crash anymore, I'll drive with these accidental mods. I also had a mod for better view of the signals which worked. That seems also to still be there. But I'll suggest not using mods if your game have a tendency of crashing. The is a bigger update announced to get rid of these problem, so let's hope it does. For me, I'll just wait see. And I won't add any mods. I learned my lesson.
