I have been getting this problem like about. Every Single Game. After some couple minutes, i got kicked out and an error message stated "Connection to your opponent has been lost, you have been signed out." its getting annoying. Anyone have any ideas how to fix it?
Thanks.

I have the same problem.This is really frustrating.Can anyone help?

This happens to me only when I choose servers mannualy. On Quick join, never happens. The Quick join selects for me only 3 servers, always. If I enter mannualy on those servers, I can play and I'm not loosing connection.
I think the Quick Join selects the best servers with the lowest ping. If you enter other servers, with a higher ping, the server kicks you out.

Too many enemy players quited and the game cannot go on. Guess you went maxima pwning eh?

Did you automatically signed out after you got the error?

Im still having the freaking problem.. or isit that i just signed up in the game?
Its annoying the heyl out of me.... balls..
Plus the quick join solution. it still kicked me saying the same message... Im going to have Rage.

Dudes, theres another thread like this, post this problem there.
