EDIT: can anyone tell me what exactly that error is some of you seem to get?
This is what happend to a friend: It seems like the connection is lost from time to time. But some enet_... functions are still called after the disconnect which results in an error like this:
ANet-DLL: Error in enet_clsend_event! No connection established!
