Editor won´t open in Premiere Elements 12

I suddenly can`t open Premiere Elements 12. Used it two weeks ago without problems. I can open the Organizer, but not Video Editor. When choosing Editor, new project, a purple bar occurs and keeps going. I have tried uninstalling and installing again, both in C and D-drive. When trying to open Adobe Premiere Elements.exe from the folder, it starts opening, but then I get this message: An unhandled win32 exception occured in Adobe Premiere Elements.exe [11660] (the number varies). Anyone know how to fix this? I tried the chat, but since PRE 12 is not the latest version, they couldn´t help me.
