Server: Error: Unable to startup listener on 43594 - port al
Server: Error: Unable to startup listener on 43594 - port already in use? how is that possible?

thats got nothing to do with us u just clicked start server twice

have a firewall or router? could need to set up your firewall or port forwarding on router

this has nothing to do with the router he just clicked start server twice instead of enter

no, thats what happened to me, it kept doing it untill i set my router to do portforwarding... it may not work for him, but thats the problem i had, and thats how i got it fixed
