hey if you are getting the message "you were kicked from the server" while origin synchronization i fixed it in the following way.

delete all of arma 2 and arma 2 OA then delete the registry entry for OA, then reinstall both

hope i could help (reply on this thread if you want me to step through this solution)

I added you on steam for help.

I suspect you are trolling. That's like telling someone to "format c:" back in the days of DOS. Only an idiot would try what you suggested.
