Some people find it easier to reset the preferences file by going to Edit>Preferences>General tab and clicking the Reset Preferences on next launch button.
What I suspect is happening is that the program is not closing properly and the process remains active. You can check this by looking in Windows Task Manager and seeing if any Elements Editor process remains open. The reset of the preferences file may fix this problem. If it doesn't, I would suggest doing a complete uninstall and reinstall of the program.
