Vitdom,
I did try to verify game content through Steam, nothing got detected. I re-installed arma 3, nothing changed. I've checked for pc updates and made sure Arma 3 is up to date. Is there a specific update I should check? I never overclocked my pc, I had built the pc myself. I used to be able to play Arma 3 without any problems, the last time I played Arma 3 was like 3 or 4 years ago on the current pc with the current pc parts. I have just tried a couple different MPs, it would load the game, I would select what team to be on and click start, got the error. The first MP I tried, I would walk a few feet and get the error. The second MP I tried, I spawned beside a heli, got in it, started the engine and got the error; it did like a small lag then the error popped up.

After I choose a server to join and the game is loaded, I lose my audio. I do hear gun shots, running, nothing.

I restarted my computer because it had a Norton update. Now I don't have audio...

It validated 3 files and said it was validated successfully.
