Photoshop error message on old computer

Look I am on a fixed income and can't afford a new computer nor will I ever be in a position to do so. Please stop telling me to update and leaving popups blocking me from working on my images. I am now in a positions after using Photoshop since version 4 it has become a burdon on me financially to to continue to use your products. So the more stressful you make it for me to continue the easier your are making me decide to close my account. I hope to beable to continue working with Photoshop until my old computer will no longer open any files.
