me, too it worked this morning on another computer, i come home and 2 hours alter it doenst work. I also have previously had it working on this computer maybe a few days ago....

for the record it says v0.0.0.56 not .55 which is the last version i can find listed on the site, not sure if this is the one i was running on the other computer....

never mind, i uninstalled, restarted, reinstalled and it seems to work fine.

but when i uninstalled and reinstalled without restarting it didnt work, meh whatevers :)

Sometimes Xbox.com (or Passport - err - whatever they want to call it this week) may have an issue.  I'm still working on getting XBF to handle all of these in a better model; though it's difficult to test everything accordingly.

If you encounter such issues, make sure that you can indeed use your browser to visit http://www.xbox.com and successfully sign in.  If you can and are still having problems, please send me what URL you end up (at Xbox.com) and, if applicable, what language / version of Windows you are using.

I think I might have narrowed it down some.  It seems to happen when the gamercards are refreshing.  It hangs mid-update.  Once it hangs and you exit friends you can't get on friends or xbox.com.  My work-around detailed above still does the trick in the meantime.  Also if I have the sound on my PC turned up, I can actually hear it clicking as if I was changing or refreshing web pages.  Hope this helps.

Great.  I'll see if I can track things down this weekend.
