I have tried to download and install 1.60 but it says "! C:\Users\Taylor\Downloads\ARMA2OACORFT_Update_160.zip: CRC failed in ARMA2OA_Update_160.exe. The file is corrupt" EDIT: My game is updated to 1.60 but I still can't play anything else I should try?

I bought Arma 2 COa few days ago to use the mod and I have been trying to use six Launcher to play but it gets stuck on as far as I've seen the last loading screen It makes it through everything else fine then freezes any help or know what I could do? Would really appreciate it the game looks fun!
