HOW TO - Downgrading to 5.02 or prior from 5.03 or later -very risky
 

<p>Version 5.03 and above "index" some fields in the Singers.mdb and Songs.mdb databases to speed up searches. version 5.02 and prior cannot use these databases. Follow the steps below if you ever downgrade to a Hoster version prior to 5.03.</p>

NOTE: If you get an error stating "Incorrect Parameters" while trying to build your songs database, this means that you have a damaged kma or .kmh file. This may not allow you to return to a prior version. The current version has more error checking to skip this, and write the bad file to a list.
