Premiere Elements 13 won't open

I have a photoshop/premiere elements 13 package installed and about a month ago the premiere part stopped opening and giving me the following message

Premiere Elements 13.0 has encountered an error.

[/Adobe/pre/main/MediaCore/ASL/Foundation/Make/Mac/../../Src/DirectoryRegistry.cpp-283]

I have seen this problem posted before but haven't actually seen a fix for it that I could follow.

I have uninstalled the programme a number of times but it still persists

In my case the problem only exists under my user ID, I can go in on my wife's account or as guest and run the software perfectly which has been my saving grace in the last few weeks, however not very convenient.

I have only basic tech knowledge and a lot of what I have read here leaves me baffled, I really need someone to support me through this please and I am pretty much disgusted that Adobe aren't intrested in helping with a product that is only a few years old.

Any help much appreciated. I am running a Mac info below
