I hope someone can help me figure this out. I bought arma/dayZ for myself about a month ago and it worked just fine. I have two laptops, so I installed the game on both so I could play wherever I happened to be. I wanted to play with my brother, so I went on my second laptop, logged into my brother's steam account, and purchased arma II again. After reinstalling both games, he still enters a server as the same exact character as I am from my first laptop, and I am unable to join the same server as him. Apparently the game still thinks that he is me, even though I bought Arma again and reinstalled everything. Any suggestions? Thanks!
