When upgrading to pro it's often a good idea to delete your LW prefs. Try deleting your LW Preferences folder whilst LW is closed; instructions here: Point #2 & 3 in Fixes for Limewire (sample image included at bottom of page.)

After re-opening LW, you'll need to reset your options. But deleting LW prefs often gives LW a fresh breath of life. You didn't say what your previous version was so the differences might be well worth the deletion of prefs.
