Arma 2 steam first time playing

[Nickh118 0]

i download arma 2 and installed it and everything blah blah blah.... then eventually a little screen popped up saying "data file to short ' addons/sound.pbo'. expected 389161532 B, got 283770880 B '

anybody knows what this means OR knows how to fix it?
