I had the same problems with the themes. the only way i got them to work was to:


create a new folder in limewire/theme folder and name it the theme you have downloaded eg: red_theme.
extract the zipped file into the new folder you created.

within the limewire/theme folder copy any of the lwtp files that are already in there and paste it in the same location, then just rename it to the theme you have downloaded eg: red_theme lwtp.

hope this helps
