When I download and run the Lan server, TASServer_034.exe, it opens for a second and then closes. I managed to get what it said:
Exception in thread "main" java.lang.UnsupportedClassVersionError: Bad version number in .class file
at java.lang.ClassLoader.defineClass1(nativemethod)
at java.lang.ClassLoader.defineClass(Unknown Source)
....
(long string of errors like above)
....
at java.lang.ClassLoader.loadClass(Unknown Source)
at java.lang.ClassLoader.loadClassInternal(Unknown Source)
Anyone know what I need to do to fix this?
