Songbird won't play any songs

Songbird won't play any music. Music lIbrary loads fine, etc. When I start Songbird, I get the following warnings:

Failed to load XPCOM component: C:\Program Files\Songbird\components\gst_libs.txt
Failed to load XPCOM component: C:\Program Files\Songbird\components\kPlaylistCommands.jsm
Failed to load XPCOM component: C:\Program Files\Songbird\components\sbAddToPlaylist.jsm

Failed to load XPCOM component: C:\Program Files\Songbird\components\sbStorageFormatter.jsm
Failed to load XPCOM component: C:\Program Files\Songbird\components\sbTimeFormatter.jsm

and then an error in a pink background:

Error: formatURL: Couldn't find value for key: 20and
Source File: file:///C:/Program%20Files/Songbird/components/sbURLFormatter.js
Line: 264

Followed by 17 warnings that read like:

Warning: Expected declaration but found '*'. Skipped to next declaration.
Source File: http://getsongbird.com/css/songbird-1...
Line: 195

each with a different line warning.

And finally, I get the error

Error: Permission denied to call method Location.toString

I've tried uninstalling & reinstalling Songbird with no luck. My PC is running Windows XP SP3.

Thanks for helping me out.
