hampa would be the person to sort out purchase errors/hangups. You can PM him, but waiting for him on our Chat tab will get a response much quicker. If you know how to use IRC, our server is irc.toribash.com, room #toribash.
hampa was active on irc a bit earlier. You can come here and wait for him while you do other things. http://forum.toribash.com/chat_view....annel=toribash
There are other people in there (me included) if you want to burn time while you wait.
