it was on nipper opus right? that's one of the reasons why I can't stand that level, the other being that it's boring to me... but yeah, kicked more than 2 times during that time, then i decided to give up....
it was probly steam there fing up there and there every now and then try restarting steam and theres something in the FAQ forum about how to fix this when it happens
Please tell us what message you got when you got kicked. Was it something like this "Kicked by Console?"
