The Spring Client still has my battles up!

[FizWizz]

A couple of days ago I tried hosting a game for myself w/ the Evolva mod just to see what it was like, and then I got a funny "Error: server [is sending 'ambiguous commands' or some bull like that" notification. Much to my annoyance, my games were up (I tried twice) but when I joined I was no longer the host, so I couldn't launch or close the games. It's been a couple of days and the two games are still up, and quite frankly it is embarassing...
Can someone reset it or something to get rid of the battles? if getting in matters, the password was 'private' for both of them (yeah, real imaginative, I know), but it beats me what anyone could do from there.

[edit]Okay, someone solved the problem, so hey, thanks
