Quote fromQuote fromNot the rar, the jar. You open the jar with winrar, and drag the classes out of the zip and into the jar.
"Error: The archive is corrupt" I got this when I opened the ZIP file in winrar and the .jar file. Then I dragged a class file from the ZIP into the .JAR and got that error. I also tried an unzipped version of it but it didn't work.
Have you attempted to download a fresh copy of the file? Also, exactly which one does this error come up for when opening?
