Help With Monster Server!

[and3212]

Okay so whenever I try to run a Monster server this comes up

2014-01-19 09:44:17 [INFO] Starting minecraft server version 1.6.4
2014-01-19 09:45:23 [INFO] Loading properties
2014-01-19 09:45:23 [INFO] Default game type: SURVIVAL
2014-01-19 09:45:23 [INFO] Generating keypair
2014-01-19 09:45:24 [INFO] Starting Minecraft server on 192.168.X.X:25565

It just stays on the last line, have let the server load for an hour, I have re-downloaded it several times and I have no idea what I am doing wrong.

Here are my Specs -
Processor 2.5 GHz Intel Core i5
Memory 4 GB 1333 MHz DDR3
Graphics AMD Radeon HD 6750M 512 MB
Software OS X 10.9.1 (13B42)

~Thanks!

specify -nogui after the -jar ftbserver-1.6.4-165.jar argument in the startserver.bat file
i.e. -jar ftbserver-1.6.4-165.jar -nogui
