As per my understanding, you've both PRE 11 as well as 14 installed on your machine. By default, if Organizer 11 is used then it would open PRE 11. If you want to use PRE 14, then you can provide the path of the "Adobe Premiere Elements.exe" in the Edit>Preferences>Editing>Use supplementary editing application. This will lead to PRE 14 being used for editing instead of PRE 11.
Please tell us if that works for you.
