When you said extracting to the .jar, did you do this?
1. extract the zip, and put all the class files and the TyberMod folder directly in your .jar
2. Or did you just take the entire extracted folder and throw it right in the .jar
If you did the first one, i have no idea, it should have worked, if you did the second, Look at the first. --- MH Tri: Zuko /// Favorite : Barioth /// Least favorite: Great Baggi MH Freedom Unite: Vladimir /// Favorite: Ukanlos /// least favorite: Iodrome
