Well, I have to say. 4 days and no response. I managed to log on with some trouble, last night. However my GF can't. Today, on the other hand, has been nothing but connection errors. We can;t play Dawn of War II together in Co-op and she's having problems getting things done in Fallout 3.
I'm glad that PC gaming is dropping GFWL, it always reminds me of the two and a half hour annoyance I had trying to run Lost Planet 2 for the first time. The constant updates and having to sign in every re-start.
Personally, I'd like some word or the problem fixed. After 4 days, on the other-hand, I can't see much being done to get this repaired quickly.
