I have Acrobat XI, Photoshop 12 and Photoshop 14. They have been running fine for several years. Yesterday, all three ceased operating - all returned the same message - need to download Application Manager to resolve the issue. I have tried, but the Application Manager files that download will not run. I now have three programs that will not run and one supposed Utility that will not setup. Can anyone shed some light or should I just buy another Photo editing program?
