I was trying to play Fable 3, and login to my GFWL account.I enter the Username and Password and then a windows pops up saying "Downloading Profile".
Now after 2-3 minutes I encounter an error "The Live Service may be unavailable or there might be a problem with your firewall".
What should I do???
These issues are caused by some sort of network interruption. It could be firewall based, router based, or just another program interfering with the network connection. Norton Internet Security, for instance, will frequently prevent people from connecting. Also, some sorts of anti-virus software will cause issues.

Also, dissable your AV and run a Clean Boot(Bing it).
As always, Play Safe!
