Buying a new computer, how to transfer license to it

[edwillia]

I purchased a new computer, how do I transfer my license to this new computer or do I have to buy a second copy of it?

Install the program, go to Help->Register, and fill in the key from your purchase email.

Assuming the old computer hasn't cratered, you can also copy the key out of the Help->Register window on the old one, paste it into a text file, make that text file available on the new computer, then use that to copy/paste into the new install.
