Description

I was playing less than 24 hours ago with no issue. Not sure if there was an auto update for a particular mod but now my game won't start and I am getting this error message. Can't exactly pinpoint the problem from the message. Appreciate any help, thanks!

Reinstalled another version of a mod that must have auto-updated. Got it resolved.
