Can anyone tell me what the heck I'm doing wrong?

[Gilberreke]

Which program do you use to open up the jar?

[Triskelli]

jZip... Which one would you recommend?

[Gilberreke]

7zip is pretty much the best one out there. ZipException basically means your JAR is corrupted, which is usually caused by using a bad program.

Alright, trying again with 7-zip, but how do I copy and paste the files? ctrl+c, ctrl+z isn't working.

Got it! This thread can be locked if need be.
