Boy I hope people are still on this server helping out. Okay so I tried running the FTBServer-1.6.4-965.jar and it doesn't open the window. I am running Windows 8 with 8gb RAM 2.4GHz Quad-core and current Java and Java 64-bit. All it does is generate a notepad file and a .LCK file which is empty. This is the contents of the notepad.
