I'd like to downgrade my player from 2.00 to 1.03 due to inconsistencies in the music database so it can rebuild itself after upgrading it again to 2.00.

do you know of any source where I can download version 1.03?

I've found this description in an earlier post and it describes my issue quite closely:
"then the player hangs on the "synchronizing" screen,
I reboot the player, it then takes a LONG time on the "Building Music Databse" screen, eventually it boots, I then connect with emplode, it says "checking disk integrity" which takes a while. After which it boots, and says there were warnings, looking at detail it said playlist size is smaller than number of childs. So I do another Sync, it then works fine.
I then tried testing by uploading 1 song in a playlist, it threw up the same errors as above, rebooted and same situation, it did a "Checking disk integirty", took a long time. After syncing correctly, then deleting the playlist which error'd before, I resyncd

then:
Try doing a full downgrade to 1.03 emplode and player, then see if you can fix it by re-synching."

thanks for your help guys!
