Trouble with REGISTERING...HELP!!

Hi helpers. I’ve paid to register and I received my License Key via email.

In the box that says “Serial Number Name” I type the email address that my program is registered to.
In the box that says “Serial Number” I type the License Key number from the email I was sent after I paid.
I get the following error message:

I’ve checked many times and yes, they do match.

Can you please help ASAP?? If the trial version officially runs out then I will be without Scrivener, which would be bad bad bad.

I just checked my registration email etc, and my ‘Serial Number Name’ is my name not my email address.

Other than rechecking your email the only other thing I could suggest is raising a ticket. Support from L&L in my experience is pretty good.
