for anybody that has tried online, did anybody get an error message win or lose:

"A connection error has occured during the match. This match will be invalid."

Out of 15 or so fights now win or lose I always get this after the match. At first I thought it was rage-quitters but then I started losing and got the same message. The game still tracks my record though, but it seems the servers won't acknowledge my record when i try to check my rank.

You might want to check the game web sites forums. I bet you aren't the only one having the problem and there may be a message from the developers there.

Here a link to their forums. I was looking through it a bit and saw your problem but as far as I saw there wasn't a good answer for why it's happening.
