Problem Direwolf20 Server crash on start

[imsomeguy]

Whenever I try to launch the ServerStart.bat, the command prompt appears, then disappears almost instantly without starting the server. No crash log is generated, but the following flashes in cmd before it closes:

C:\Users\Matthew\Desktop\Direwolf20_1_5-server>java -Xms512 -Xmx1G -XX: PermSize=128m -jar ftbserver.jar
Exception in thread "main" java.lang.NullPointerException

(Disregard space in -XX: Perm)

I tried redownloading the pack at least 3 times, through both the launcher and the FTB website. I have also tried reinstalling java.

EDIT:
Used pause to get the text directly, sorry if i misunderstood what you wanted
