thanks also maybe issue a new key when terragen 2 goes gold,
ie so the current key will not work when terragen 2.00 is released?
it maybe hard for jmclusky as I heard the key process is manual.
a simpler option would be to block the 2.00 update via the helps/check for updates
and have it only so you can download it via the email you receive
a third option i recommend is that you incorporate a second key system ie a serial that you paste in once right after you install terragen just to add a little extra security,
the reason for this is that a person may take a copy of terragen 2 (plus the keyfile) from his or hers work post it on the net but since he didn't receive the email with the first unlock code he won't be able to start it. just another idea
