After loading in to a mission in multiplayer (evo, coop, dom) after about 15 seconds of running around usually, I get a black screen saying 'Receiving...'. This screen does not go away and the word 'Receiving' begins to flash jerkily. This does not happen in Single Player. I have... Vista Home 64bit Nvidia GTX 285 1g, 6 Gig Ram, 22 Inch monitor. ArmA 2 patched up to 1.02 I have the latest drivers and windows updates. My PC is BRAND NEW. Can anyone help?

I could have chosen to post a reply in an existing thread - however this problem is actually different to the ones i have read about in the first 5 pages of this forum, which is why I instead chose to make a new post for a new problem. But I fixed it I think - I needed Service Pack 1 for vista
