Bug
Ok first of all, I lost my exp which is to expected becuase of the update.
But...
Normally it's connecting to games fine except since you did the update. I tried connecting to someone called Guest101 and it said it failed and it;s restarting search. Two secodns after that, the guest left.
Then to test it, I used IE to open up another version and tried playing a game against myself.
On my firefox screen it said unable to connect, restarting search like before. But on the IE screen, it froze...
I the tried making a custom match but on the IE screen (the one joining), it said unable to connect.
Oh and I think you should stop people of the same IP playing quick play matches but if you could, allow them to play custom matches.
