hmm.. maybe it has something to do with installing pro after /over free limewire?

did you uninstall free limewire before installing pro?

maybe you could try to get rid of everything limewire related

• uninstall limewire
• get rid of the .limewire folder in your Documents and Settings/username folder
• trash the 'limewire' folder in 'Programs and Files'

and then clean reinstall pro.
