New registration key help needed ASAP

My installation of Home version 4.x is set to expire on June 16. When I try to update it per the red popup warning box, I get the screen to select an upgrade or re-register. This does nothing but hang, and I have to ctrl-alt-del to force it to close. I’ve just been to your website to see about a new registration key, but the page it goes to says “The document contains no data.”

Can someone help me get a new license key before the program expires? Thank you.

Go to this page and click on “I’m a registered user and my registration key has expired, I need a new one” and follow the instructions.
