Hmmmm .... there is no such thing as a two year subscription to Limewire .... There are a lot of scam sites who sell one year / 2 year / lifetime subscriptions
a large chunk of mails on the subject is here.

Limewire basic is free and pro costs $18.88 for sixth months support and updates.It is avalilable here
http://www.limewire.com/english/content/download.shtml
in any event, and I know you may have had limewire from the official site and got the time lengths wrong ... I would go to the above site and DL Limewire basic, check it works well for you and then upgrade to pro if you wish.
Also unless you paid for limewire pro within the last 6 months you will no longer be able to update it without paying again
I hope this helps
