DraftSight activation with professional mail address

Hello,

We have difficulties to activating DraftSight in our company.

We made several tested that allow us to infer that the acivation does not work with all email addresses.

Indeed, during the execution of DraftSight program, the software asked to Register with an email address. With a standard gmail address there is no problem, we have the windows that the email has been succesful send.

However, when we do the same with our company email address, we have no message confimation that Email are send. The application starts, but each restart of the application, the software asked to Register.

Note: This is not a problem with our mail because a registration has already been done once. But since, we can not register others.

Have you a limit to the registration that is linked to our domain (@ domain.com)? Is it possible to remove this limit so that every person in our company can register the product with the professional email address?

Best regards.
