Poor Dottie. I truly sympathize with you.
My advice, find one of your games that you enjoyed, reinstall it and play that one. The original Black Mirror was a CHARM (except for the suicide thing). The puzzles, the graphics,the story, even the rain. Whenever a game made my head hurt just to load it, it was never worth it to play.
My Hewlett Packard is an awesome XP, but when it shakes its figurative head 'NO', I must agree.
