Are you trying thru their webpage or via the store you bought it from.

Hi, trying through the automatic updater that shows when I try to use the program. Says this program needs an update and so I click on the link and nothing.

Hmm, there isn't an auto updater, is it not instructing you to go to the downloads page?
