Arma 2 corrupt files and DayZ Memory errors?????

[UMBRA]

OK heres a basic breakdown of whats going on:
I've had everythign working fine however i get kicked alot when trying to join serves for dayZ and it ususally takes 3 tries to get into a server before i can actually play on the server. So i check my game cache and have a couple messed up files so it downloads the corrected ones then i recheck to make sure and 2 files are still not fixed... so i try it several more times but still 2 bad files... so i uninstall arma 2 and reinstall... same problem... so i uninstal battleye and try to redownload battleye and i get a error saying my game files are corrupt. so i do the whole process several more times with the same result of corrupt game files WTF? Im no ididot when it comes to computers but this makes no sense..... any ideas?

Also what started this whole fiasco was i was getting a battleye memory error when joining my normal server today
