I have steam versions of Arma2 1.08 and OA 1.55 on winxp.
After patching to 1.55 i had the "BE failed to initialize" error, BE 1.45 update fixed that.
I now see BE initialize when i join. But I was kicked for "Corrupted Memory #0" by BE, restarted PC tried again "Corrupted Memory #0".
So following BE's instructions i checked for Viruses and then I used Steams "Verify integrity of game cache" on both OA and Arma2, now i can't join warfare servers (which is all i play) I'm kicked for "CAWheeled_btr_90 warfare2vehicles" deleted, and thats before i get to find out if i'm still going to get kicked by BE's "Corrupted Memory #0".
So before 1.55 i had no issues and played daily.
Now well.. getting pretty PO'ed.
PS I did notice Steam had done a small update for both OA and Arma2 of 3.2mb each, no change.

OK "CAWheeled_btr_90 warfare2vehicles" deleted error is because CO wasn't launching even thought thats whats i'd ask it to do it was just launching OA, i guess this is from the "Verify integrity of game cache" check i did, both Arma2 and OA must be run after this check, otherwise CO won't start it'll just be OA.
So now i'm still being kicked for "Corrupted Memory #0" by BE.
Done Virus scans what else is there to do about this?
