Java Problem?

[andejoe1]

Hey, being a mac user I've been a big fan of your deck builder since you released it last fall.

I'm writing because in your most recent versions the JAR file will not open and an error message pops up,

"The jar file "DeckBuilder.jar" couldn't be launched. Check the Console for possible error messages"

I'm runing a Powerbook G4 with all software updated and the most recent version of Java. Any advice would be every so greatly appreciated,

thanks,
Joel

exception in thread "main" java.lang.UnsupportedClassVersionError: Bad version number in .class file

I just figured out how to get it to run. See this post:
