The current Beta key is expired, there is no updated key, and even if you want to purchase the new version, the purchase page doesn't work. This program now looks like abandonware.
The only way I can make it work is to temporarily change my system date to before the key expired.

I have the same issue. The problem is, you CAN"T register if you don't already have a key, as you can't buy a key. The site to buy one is broken and doesn't work!
