Unpermitted Manipulation with Time

In RFEM 6 or RSTAB 9, I get a message saying that unpermitted manipulation with time has been detected. What can I do?


Each license includes the creation time and the expiration time from our server. From time to time, our application checks the model's change log and if it discovers that the change time is not continuous, it logs off.

For this reason, you should make sure that the system times are continuous. If you make major changes to the system time, log out first.
