Some Movavi products have a time limit on trial versions, please review the trial limitations list for more specific details.
In that case the trial lasts for 7 days since the installation has been performed.
Unfortunately, due to the trial limitations, it is not technically possible to regain the trial version after it is expired.
You can try installing the same trial version of the application to another machine.
Else, you can try a product that has completely the same features as the one you intended to try.
For example, Movavi Video Suite has the features of Movavi Video Editor Plus, Movavi Screen Recorder, Movavi Video Converter Premium.
Movavi Screen Capture Studio has the features of Movavi Video Editor (non-plus) and Movavi Screen Recorder.
