I figured I would get World of Minecraft Client wrapper and i got the other files downloaded fine but when I went to download the .jar file i get an error that says Could not retrieve main-class attribute then it says the files location. Can anyone help?

Make sure you are getting the

Make sure you are getting the correct minecraft.jar and that you are putting it in the lib folder of the client. Use the link mentioned in the NOTE, that is in the instructions for the client download.

2 problems 2 solutions?

Ok this is what happens to me.
1. If I run the run.bat as administrator I get the same error as the others here.

2. If I don't run the run.bat as administrator I can log in to the World of Minecraft client, I can pick the server and double-click it, after that I get a error java.lang.IllegalArgumentException: input: = = null!

This is what i keep getting as well. Tried all the links, reinstalled java many times. no difference.  This link shows a solution for java programmers, but i don't understand it. Anybody else?
