I got this problem too.. my mod is upto date... im thinking its because i have ripped everyfile out of the main directory and have loaded it as a module resource so any alterations i make dont affect the base game...
Tho i been runniing fine for the last week.. this problem only just started poping up yesterday.
It dosn't happen all the time i find usually after looking at items in a vendor or just leaving a city i get this C++ runtime crash it just says to contact the applications support for more info..
