If your program is Photoshop Elements, you have posted in the wrong forum. Some how your thread got posted in the Premiere Elements Forum (video editing).
Please re-post your thread in the Adobe Photoshop Elements Forum to take advantage of the specialized expertise there.
My impression is that you have gotten one of those tryout dialogs with buttons for License This Product or Continue Tryout.
If that is the case, just click on License This Product and follow the instructions. This happens using Premiere Elements from time to time.
And, just in case message, when you go to close a Photoshop Elements session, do not go to the Editor's Help Menu/Sign Out. That deactivates the program and will throw you back into the License This Product again. For closing the program between sessions, consider File Menu/Exit or the X Close button.
Please consider. We will be watching for your progress as your time permits.
