No! I didn't try yet... I was waiting for the answer from Pauli to your last question in the other thread...
So, your "EDIT: done" means it works... ok, I will try
EDIT: I tried it. Problems:
- I uninstalled DR800+
- I installed RC4
- I reinstalled DR800+
- I get the message: There was an error...
DB backup already exists (/media/mmcblk0p1/global.db.pre_db2fs).
You must delete that backup manually in order to continue, now quitting.
Can't migrate thumbnails from global.bd to file system
