hey guys i made a server for me and my friend to play on and when he connects it connects him to the server then it says invalid key and it kicks him. So is there any way for me to stop the server from checking his key when he connects, Thanks.

i am having sort of the same sort of promblem except when i try to connect to my friends server it just keeps saying "contacting server" :/ but ur promblem sounds like ur friends regristration key is wrong i believe.
