registration problem

am reposting  a problem someone else previous also had, but the solution proposed didn't work

I have contacted Stardock support 3 times with no resolution to registering the product. They tell me to try one of the following 2 solutions but neither work. When I email them again, they send an identical email with the below 2 solutions.

In your application, choose "I only have a serial" (Also known as Product Key)

Example:
http://screencast.com/t/YcVkI9tZqsrc

After entering your credentials, and serial \ Product Key (in your email receipt), click Register. (there is no Product Key on my receipt)

If you have lost your receipt, you can get it from the order page:

https://store.stardock.com/myaccount/orders

Open the csv file and the serial(s) is in there.
