Remember LW's pro support & free updates lasts for 6 months only. So if you purchased Pro within the last 6 mths then no problem.

There's a few options. One is to go here http://sales.limewire.com/support/? & another is to go to LW's support page http://www.limewire.com/english/content/support.shtml & click on Pro support link, then enter your details & then look at the link at the top of the following page for getting another copy.

If your pro support has run out, then you have the option for the free version called Basic or going again with Pro.
