until yesterday everything worked fine.
Yesterday i upgraded to version 5.0 "Platinum" version, now everytime i open a campaign, while you hear the motors starting, a message appears something like "woff.dll can not be started" (dont remember exactly) and i drop back to the mission briefing.
I already deleted my career because i thougth the career was destroyed somehow...no, it does not work with new pilots and new campaigns as well.
Quick combat runs fine.
No Mods active
Everything else is unchanged.
