Changing the registration email to enable AirGap

I have been assigned to maintain an BigFix (ILMT) installation, where the server has no connection to internet. But the people who installed it managed to use *** as the registration email, according to the masthead.
This means that airgap in non-extraction mode, site-list genereation, does not work, since the email address is not accepted.
Have tried with quotes, single and double, backslash etc, without any luck.

So my question is if it possible to update the registration with a proper email address.

I’m pretty sure that can be done, but you may need to open a support ticket to get the licensing folks to work with you on it.

OK, will try that.
Thanks!
