Hey there, I've lost my license key and want to move this to another computer. Don't know which email address I used to buy it but have searched them all and nothing. Don't want it on more than one computer... how do I find the key???
Use the "Contact Us" and explain your situation. Explain that you don't remember which email address used and give them a few they can use to check. Also your full name and any other information that you can. You should get some help that way.
If it's the older version 10 or before, you may also be able to get a discount to upgrade to version 11. All your older patterns should load with no problems.
