Oh, no! What's wrong? I might be able to help if you can name the exact problem.
For the moment, in case it's related, I can refer you to this troubleshooter I made a while back,
Shimeji QnA with Agent G. The central problem addressed there is a broken executable JAR file. Some people click on it, and it does nothing. If that's the case and you need the shimeji application instead, the QnA can help.
If it's anything else, please feel free to write me back. I'm happy to help however I can!
