I'm trying this form to retrieve my license number:

http://mgage.marketcircle.com/cgi-bin/WebObjects/MCStore.woa/wa/findLicense

...but it's not working for me.

The email I've used when registering is either one of the following:
mariano@unworkinc.com
paypal@unworkinc.com

Could someone assist me on this?

Thanks,
Mariano
