Which version of PSE are you using?
If you restart your PC, does elements work once?
Does the Welcome screen load - (that's the one that offers Edit or organize)?
There seems to be problem sometimes with the welcome screen
Try creating direct link to the organizer and avoiding the welcome screen
Use Windows file explorer to navigate to the following folder: -
In that folder, find the following file: -
Right click on the file and select Pin to Start from the dropdown list
Close file explorer
There should now be a tile on your start screen for the organizer.
Do you normally stsrt with the organizer?
