Have you asked at their forum? http://forum.frostwire.com/

If you have already, the best I can do is link you to info for LW... since LW & FW are pretty similar (though AFAIK FW hasn't released a version based on LW 5 code yet).
Maybe you'll find some helpful info anyway? If not - sorry. Somebody else might have a better idea.
