Premiere Elements 13 stopped opening

I have been running Premiere Elements 13 on my Mac OK since it was first released but recently it has failed to open and brings up the following message "[/Adobe/pre/main/MediaCore/ASL/Foundation/Make/Mac/../../Src/DirectoryRegistry.cpp-283]"  Can anyone help me rectify this please. Thanks
