Pro Version is disabled after few hours of installation


I Installed 2016 make version today and I got a message saying that I will enjoy the Pro version for 30 days however after few hrs I tried to open sketchup how ever it was telling me that I still have 30 days but it gave me the message that my Pro trial has expired.

I tried using it so it started on the make version.

I uninstalled it and reinstall it again so I am getting that I have the make version for 30 days

what can I do to get the trial of Pro active again?
