I had this bug almost a year ago. Opened a ticket at IDEA and after a couple of month trying "things" it was solved by Christmas patch. I had moved on to other games, but after news on Dayz mod I tried to enter my Arma2 game and got Receiving data bug again. Steam version, latest patch, latest BEye and nothing has changed in hardware since last bug except from now I have 24gb ram and not 6... Can't play - me sad :(
