If you have the Limewire programme (or the installer) saved on disk you can go on using it no problem.
BUT before you do..... Is this Limewire pro you are talking about and did you buy it for US$18.88 from
www.limewire.com.
If so there is no problem.
If not let us know the details before reinstalling it.
And I don't have to say, I'm sure ...make sure you run up to date Anti-Virus and spyware software at all times
