ACTIVATED SUCCESSFULLY BUT AFTER SOME TIMES NO ACTIVATION IS FOUND ON CHECKING LOCALLYAnswered

I am testing Turboactivate for a VSTO COM Add-in (C#, .Net Framework). An issue kept popping up occasionally. After a customer is activated successfully, the customer still gets a warning signal I set for Trial Periods Expiry that His trial has expired.

The only check for a trial period after checking activation getting “not activated” feedback. But activation was done successfully by the same customer. This means the software is getting “not activated” feedback even though activation was already done.

My  DaysBetweenCheck is not reached so the software isn't actually rechecking with the server for activation, the check is still at the local level.

The software has been updated to higher versions a couple of times and the only reason I can suspect at the moment for this behaviour is most probably the installation of a “TurboActivate.dat” by the user that replaces the old one when the updated version is deployed.

Please how do I troubleshoot and/or solve this issue?

Thank you.
