Démo version expired

Hello,

I have a problem... We have a Captivate VIP licence for 3 users.

For one of my user on MacOS 10.14, I don't know why, one day Captivate says the demo version has expired and that we need to purchase it or enter a serial number.

But we have a license based on user e-mail that I configured in the Adobe Administration Console.

So I uninstalled everything on my user Mac, even uninstalled Creative Cloud.

I then installed again Adobe Captivate thru the Package I built from the Admin console.

And unfortunately, Captivate keeps complaining that the demo version has expired... And we cannot use it.

How can I force Captivate to ignore this demo expired timestanp and connect to the Adobe website to verify the user e-mail and see that it is a valid VIP licence ?

Can someone please help me. I am stuck and it is becoming urgent for this user to get back to work !

Thanks for the help.
