I have used the GFWL many time from the same Windows 7 machine but there seems to be some problem now. Actually I have recently downloaded the GTA 4 and installed it. After this I tried to log into GFWL in the game in order to access some extra services. I have tried to do the same for 3 time but everytime my account going into an "Offline" status. I have checked the information about my GFWL account which is valid yet. I thought problem might be with the game itself so I tried doing the same thing with Fallout 3 but there was the same problem. But this time I have got the 0x0800705b4 Error where as connecting to the GTA4 gives me Error Code 0x80151911.
