Digikam Error

Hi, I've just updated my system from SuSE 9.3 to 10.1, but when I start DigiKam, I get the following error message: Failed to update old Database to new Database format I've tried deleting db files where I could find them, but to no avail. It will run without a problem as root, but not as a user. I need some guidance, please. Thanks, Craig
