The real LW was never 29.95, but some scam sites might have charged that, which could explain why the email addresses don't work at www.limewire.com.

However, even LW's Pro version is only updateable for 6 months, so your upgrades would have expired already.

Anyway, the most recent LW is much better than it was a year ago, so you are still ahead of the game if you download the free version. http://www.limewire.com/english/content/download.shtml
