As the topic title states, I'm unable to connect to the GFWL servers. Whenever I try to sign in, I get an error message reading "The profile cannot be signed into LIVE. There may be a network problem or the Windows Live ID service may not be available."
From what I can see, the LIVE service is available. I've also tried basic troubleshooting solutions like restarting my modem, router and computer but to no avail.
I was able to sign in just fine yesterday evening and I made no changes to my system since then.
