I had the album art and album list panels on my sidebar but I recently re-installed foobar and now when I right-click the sidebar, there is no option to show the album art or album list panels. How do I enable this? The database is enabled... thank you

It sounds like the .dlls just aren't present. Did you install to a different directory? And if it's 0.9b3 that you installed, the old components won't work.

If you have the album art & list panel plugins/dll's installed, and aren't using the beta -

Make sure you have the latest version of Columns UI ... (version 0.1.2)
You can check the version # under Preferences -> Components.
Some installers don't include the latest version.
