Know this thread is a bit old now but this isn't working for me and it's good to know how to delete preferences.

Just FYI
OS: Vista
LIMEWIRE VERSION: 5

My current problem is with it freezing and obviously this is one of the first suggested solutions.

I've followed all instructions, made hidden files viewable (and I know it's worked cos I can view other hidden files), gone to appdata/roaming/limewire.
When I get there though there is no preference folder.
I have these folders:
.AppSpecialShare
browser
certificate
mozilla-profile
promotion
themes
xml

I then have just a bunch of other files. Are these the ones I delete perhaps? A few of them are Cache files I've seen. If you need info of what files are there let me know but I'm not gonna type it up unless you need it cos it's quite long .

Thanks very much, hopefully I can get some help on this.
