I got a problem with GFWL. At first, it worked nice and allowed me to play my games on Steam normally. Then it stopped working, said I could not login anymore because of a modem or firewall problem. I started the game as administrator and solved the problem.
The day after, I got the same problem again, and I haven't been able to solve it since, as if I start the game as admin, I get error 0x800705b4.
Does anyone know how to solve this?
