I and my friend have this problem too. We can't collect  rating. The important thing is our game was not finishing. In the middle of our game connection breaks. Then we press reconnect button. We can connect server again but game don't go on. :(

poor internet connection maybe

maybe your connection is restarting every so often (i'm not sure if that's possible but i believe it is)

and then sometimes its just down to luck
try closing other programs such as other web pages or msn etc. that may be using bandwith

might help 
:)

Delete all cookies and temp internet files.. does this help? If so, it's spyware causing the problem.

shut up you iv had just about anuff of you beppe. do u think we dont no that but its the site ? 

errmmm i kind of respect him more than you so i don't see why he has to shut up....

spyware could well be the problem he made a perfectly valid point there's no need to have a go at him

Don't worry pro.loser, not a single moron like yourself who thinks they know more has ever turned out to be correct. You are not smart enough to change that trend, so shut up if you haven't got anything to say which backs you up.
