I would advise you to do an extensive read within these forums re: threads and posts on the merits and problems associated with upgrading LimeWire.

I do not mean to say that you should not perform an upgrade but, that it would be wise to get some background before you decide... Make especial note of any problems that others have had regarding older Operating Systems and Java installations !

btw, the updates should be free unless you are updating an older Pro version.
Never part with any money for any offered version of LimeWire that is NOT a Pro version.
