everytime i try to open vendetta i see the loading screen and then this message pops up. It worked last night after not working since the update, but now it isn't working anymore.

already checked for viruses and such, the odd thing is vendetta works fine but the warning wont stop coming up and if i try to close it vendetta closes

Do you have sound in Vendetta when this happens?

Ah yeah, it may be the sound thread crashing.
(re-asks a1k0n's question)

hmm im not sure if the sound works last time i played i was listening to music and just chatting at the station and today it didnt pop up
