I've been looking around the support, but theres no solution on any of the posts. My problem is that I've downloaded the jar file, I copied and pasted it into the lib folder of the, client, but when I try to run it I get the error message saying that it can't find the file. I'm trying to get flying and speed hacks for minecraft classic. I'll explain everything I do explicitly, because I probably overlooked something since I'm horrible with computers. I downloaded the client from the page here: http://www.worldofminecraft.com/Minecraft_Custom_Client_Wrapper_Download#comment-form

and I then went to the official website and downloaded the .jar file. I opened the containing folder, copied the file, went to the client, and pasted it in the lib file. Then, I went to the run.bat part of the client, clicked run, and ended up with the error message. I'm using windows seven and firefox (which probably doesn't matter) Any help would be greatly appreciated
