Yes, I do still have the old computer, but I didn't replace my monitor. So... I have to disconnect my monitor from the new machine, then hook it up to the old one, then switch it back. I thought it would be easier to get my key from support. The monitor's an old CRT model & it's not easy to move... plus I don't have a lot of space to work in. The instructions when installing the software tell you to contact: orders@wnsoft.com for lost registration keys. I've done this twice now. I'll try sending the same message to the address you offered. Thanks for your suggestions!
