Ok guys, Thanks.
On my Windows XP computer the themes folder can be found at

C:\Documents and Settings\Eddie R\Application Data\FrostWire\themes.

I copied the LWTP files from
C:\Documents and Settings\Eddie R\.limewire\themes
to the Frostwire themes directory

and now I'm able to use the limewire themes.

I'm still having trouble with Halloween theme from Frostwire. When I Unzip it am not getting a LWTP file. I'll figure it out though.

Thanks again....
