I seem to be having quite a bit of trouble with regards to downloading skins.. it just doesn't work. The directions on the webpage just tell me to right click and send it to the "themes" folder, but I checked the limewire folder and the "themes" file doesnt exist. So when I download skins, limewire doesnt pick them up.

Can someone please help me ! Plain white limewire is so dull !

For XP C:\Documents and Settings\your username\Application Data\LimeWire\themes.
The Application Data folder's hidden by default, so you'll have to show hidden files & folders first...start > control panel > folder options > check the 'show hidden files & folders' button > apply > ok.

For Vista C:\Users\your username\AppData\Roaming\LimeWire\themes
The App Data folder's hidden by default, so check out the thread below about how to show hidden files & folders & how to find the preferences folder in Vista (the preferences folder is named LimeWire & the themes folder should be within that).
