DM41 CORRUPTED BY MY BYTE GRABBER

[Condo]

I've really enjoyed trying out synthetic programming on my DM41. The reset button is so much more convenient than taking out the batteries of my old 41CX. Anyway I loaded the Advantage Pack and was using the Matrix functions - but forgot to disable the LN key to BYTE grab. The result is that pressing that key seems to have corrupted the MATRX application.. I first tried the reset button. I tried unplugging the module and deleting from flash. Bringing the application back still shows corrupted. I assumed the application pack was copied not moved. I'm sure its a straight forward fix, could someone enlighten me?
