Hi all..
Well in case of evaluation versions of the software, clock and date settings of the PC are really important. Since the validity of these versions is a finite time period,starting from the time and date the software was installed, if the system time and date settings change, the softwares don’t run.
Also, John… once your 30-day trial ends, similar messages should be expected, because then the software looks for a license to keep running, which if it doesn’t get, it gets terminated
