Hello I know many (if not half) of the people on the World of Minecraft support forum are looking for the solution to this problem:

Is there no way to fix this? I put java in right folder. I have absolutley no idea whats wrong with it. I need these hacks to become an op. Thank you in advance.

(I have a P.C.) If that helps.
