I purchased the Deluxe Upgrade this past Sunday, recieved an email with the key file today, Wednesday. I cannot run it within windows (get an error message) and if I try to load it in the video builder pop up that says "Load Key" I get an error message that it is an invalid or corrupt key. The instructions I recieved are below: "I have attached your register key to this e-mail. Please, save the file to any folder, rename it to pte.key and run it to register the program." I have waited 4 days for the key for the upgrade and I cannot get it to install. Can anyone help? I am already 2 days behind on finalizing this project to DVD. Thanks In Advance
