i was given an invite for the carom torny so i took it but i was in a game at the time. Then it said

'a game has just started if you leave now you will automatically lose'

i didnt leave the game i dunno y it didnt do that and i no longer had an invite and could not play someone please expalain

Invites for tournaments are sent only once. If you reject the invite, you won't get it any more, and you won't be able to join your tournament game any more.
I suppose that your choice to not leave your current game was interpreted by the system as is you had rejected the invite, because you selected the invite and finally didn't accept it.

a tip for you vendetta, only press to leave when the result as come up otherwise it will always do that you said.

omg this just happened to me

no blutch i accepted it then invite dissapeared and it said if you leave now you will automatically lose

I'm sure if you write to Gordon Brown, he can get this atrocity fixed. In the mean time, carry on playing regular games. If you think entering a tournament may be too risky, FOR THE LOVE OF GOD DON'T.

K, sarcasm out of the way. That problem has been known for a while and Nick, I'm sure, is looking into getting it sorted.
