Topaz Monkey, make sure to do the following things which were already listed by others in this thread:

- Make the player start without a playlist.

- Make sure your config.ini file isn't hosed.

But because your player has the "building music databases" error, you'll also need to fix the corrupted database. And since you're a version behind, definitely make sure to upgrade to the latest version because it fixes some of the bugs that may have caused the problem in the first place.
