First off, I have tried the solution in the FAQ, didn't work. Here's the Error. [INFO] Starting Minecraft Server version 1.3.1 [INFO] Loading properties [INFO] Default game type: SURVIVAL [INFO] Starting Minecraft server on -:25565 [WARNING] **** FAILED TO BIND TO PORT! [WARNING] The exception was: Java.net.BindException: Address already in use: JVM_Bind [WARNING] Perhaps a server is already running on that port? Also for some reason my IPv4 Address is now different, I think my ISP changed it. I dunno if that has anything to do with it. If anyone can help me I would be so happy! Thanks! EDIT: I notice everytime I try to run it I get a Crash report my OS Is Windows 7 Home Premium CRASH REPORT ---- Minecraft Crash Report ---- // My bad.
