This might be your problem:
It seems you have no "\" to designate folders in your e: partition
<playlists>e:appsxbmpplaylists</playlists>
<thumbnails>e:appsxbmpthumbs</thumbnails>
<bookmarks>e:appsxbmpbookmarks</bookmarks>
<subtitles>e:appsxbmpsubtitles</subtitles>
<imdb>e:appsxbmpimdb</imdb>
<home>e:appsxbmp</home>
perhaps this is what you're trying to achive:
<playlists>e:\apps\xbmp\playlists</playlists>
<thumbnails>e:\apps\xbmp\thumbs</thumbnails>
<bookmarks>e:\apps\xbmp\bookmarks</bookmarks>
<subtitles>e:\apps\xbmp\subtitles</subtitles>
<imdb>e:\apps\xbmp\imdb</imdb>
<home>e:\apps\xbmp</home>
And everything that references folder location on your e: partition should have the "\" forward-slash.
hope this helps.
ps: when you updated the media player, did you delete the old configuration xbmp saves in UDATA and TDATA ? Before you run xbmp 2.3, goto MSdash and using the savegame editor, delete the xbmp save configuration. then launch xbmp 2.3 again (it creates a new configuration save file)
