Problem with starting my server

[lambor009]

I'm having a problem with starting a server... I've got the 3.1.1 build... I've watched tons of youtube vids and followed all instructions, but im having a problem. It doesnt seem to be generating worlds and the server.properties file . It has something to do with nether ores... it stops the whole thing... i assume thats cause their is no nether to put the ores in? Can someone tell me how to fix... or give me the 3.0.4 server jar?

Having the EXACT same problem with nether ores. It just stops doing anything and I also don't have any of those files. Im 64 bit with java 6. Heres the command prompt when i run launch:

C:\Users\CENSOR\Desktop\Tekkit server>java -Xmx1G -Xms512M -jar Tekkit.jar nogui
