I have been unable to log in to GFWL in any of my games for a while now.
Initially the connection fails. If I try to re-connect I get an error code: 0x8000705b4
I have been unable to find anything about this exact error code, the closest (Although 0x800705b4 is an XBox error code so google thinks they're related :-)
Anyways, I have opened the necessary ports on my Windows Firewall and have also enabled UPnP on my router and tried configuring NAT.
Nothing seems to work.
Does anyone have any clue what this error is and how to fix it?
