"Maybe another server is already running on that port?"

[TobGel_booster]

i do everything right, i have my hamachi on and everything, but when i try to start my tekkit server, it doesn't work, it just says maybe another server is already running on that port". yes, i have two other servers, but i havent typed the ip into the properties files on any of them, just the tekkit one, and it still isn't working.

I'm getting the same message but I don't have any other servers running.

Ok I fixed mine. My IPV4 address or whatever changed on me. go to cmd and type in ipconfig to find it
