Error 334 when entering email address for mathworks account

Hi to all
Just yesterday during an automatic installation I was prompted to create a Math Works account. when I filled in my email address, name, and activation key I got an error on my screen.
The screenshot of the error is attached below:

The error says:
A Service Error "Error 334: An attempt to create a new profile for an email address already in use was detected."
I am using this application for the first time, and I don't recall ever having created a Math Works account before.
Does anyone else has also been having the same problem?
kindly help me out to get rid of the error.
I am at my wits end now.
Waiting for your replies
Regards
Daniel
