Metalgodz,
Can you try to run this program and see if it will recover your .kma files from you drive.

Please run this and let me know if it does find them or help you get any of them back. It should work, we think.
We are trying to figure out what is causing the files to be deleted, as there should be no way for the upgrade to do this, but it has done this a few times now.
Also what OS are you running under?
