Media Engine Enabled = Exception error~!

[steamyjunk777]

Hi, first post! :p

After looking around in the forums, I've finally been able to set up jpcsp and gotten the FFVII: Crisis Core. I have gotten the Fake MPEG message, and I was told the solution was to enable Media Engine.

However, now whenever I load the UMD, I get this error: (sorry for the long mark and paste)

Exception occurred during event dispatching:

There are alot of unknown sources, is there some sort of patch or zip file I should include in the jpcsp folder?
