You're probably checking the wrong web site.
https://btcarmory.com/ is the correct address (and this forum and IRC are the best places to get help).
Anyway, if you honestly and truly can't remember the password, you'll need to use the backup you made when you first created the wallet. Save the old wallet to be safe, then delete it and restore the wallet from the backup. Be sure to upgrade to 0.96.4 RC3 first if you haven't already.
Good luck!
