For the people who are stuck, this sticky is the one that has info about replacing the gnutella.net file (plus other fixes)
If LW Will Not Connect
Teapot, if replacing the gnutella.net file is only a temoprary fix for you...have you tried deleting that old (.limewire) prefs folder?
You don't need 2 prefs folders....if you delete the old .limewire one, it won't come back unless you reinstall a version of LW 4.9.34 or older. Have you also tried deleting your new prefs folder & the other fixes in the sticky?
