Hmmm... something clearly isn't right. Take a look at your xbmc.log and see if there is any clue there as to why XBMC is so broken.

If you're using MySQL, check that the database server is still working and available as it looks like your Addons re-cached OK (addons are processed before the audio genre) but then the addon database is a local db (Addons15.db).

So either MySQL is down, or if you're not using MySQL then both your MyMusic* and MyVideo* db files are corrupt (both seems a tad unlikely, though possible particularly if you're doing something daft like path substitution).

You should be able to find more detail relating to these errors in the xbmc.log - post it up if you're not sure, but it's looking like a very sick xbmc.
