You can search for the cached recorded video file in:
C:\Users\Username\Documents\ActivePresenter\.ActivePresenterCachedProjects
Please kindly be noted that “.ActivePresenterCachedProjects” is a hidden folder so you might need to turn the “Show Hidden Files” option on to see it.
If there are video files here, you can copy them to another folder and open with ActivePresenter for editing. Otherwise, there is no way to recover your video.
