System exception while executing tweedle...

[AdamZ628]

I built the attached project using CH 11 from Alice3toJava.
Exported as an .a3w for the AlicePlayer
Opening it in AlicePlayer.exe I get this:
There was an error executing this world.
System exception while executing tweedle:Exception has been thrown by teh target of an invocation.
Should execution continue?

The screen is black. Of course I choose Yes to continue and it doesn't change from black.
I checked all the code, tested it from the Alice IDE. I deleted the audio clip bit completely. Everything is updated and AlicePlayer works with the UnderWater demo world.
Any help from AlicePlayer folks or any experience with this error?
