i dont know what it says for registergameserver it opens then close quickly, but for loginserver it shows this:

"exception in thread "main" java.lang.unsupportedckassversionerror: com/l2jserver/loginserver/l2loginserver : unsupported major.minor version 51.0...

There is more but i wont write everything down, hope this helps
