could not find main class?

[Swifty]

I am getting this message now when trying to download. I recently switched from bittorrent to azureus, and now this message keeps popping up. Can anyone tell me why this is????? thanks so much!

This is a java exception, or rather in layman terms, a program fault.
Most java executables like Azureus, need a main class to start. Without this main class, Azureus itself could not be started. Re-install ur Azureus.
