My Adobe Photoshop Elements 5 program won't open [was Bob Withers]

My Adobe Photoshop Elements 5 program won't open. Instead I get 2 messages: 1. I've attempted to access an invalid address; 2, the programme is not responding, I was able to use it two weeks ago.

I have a PC and I'm on Windows 10.

How can I get the programme back?
