Thanks for help, but downgrading to 182.50 did NOT help. Still the same f****** error.
I´ll reinstall windows tomorrow and pray for a wonder :)
The thing i wonder about is that its only the first campaign mission that crashes that frequently, other stuff runs quite good, or atleast it takes a while to crash.
May it have something to do with Night, NV googles or something that is unique in this mission?
