I purchased The Adobe CS6 and have been using the suite for around 3 years. Starting in about November, Adobe Acrobat Pro X would not open until I reinstalled and reentered the license. That worked for about 30 days, then the same issue. All the other components of the suite work fine.
When I log into my Adobe account, it says I have no products registered. When I try to register the license, it tells me it is already registered. I would have been the only one to register it.
I am looking for another solution than reinstalling the program AGAIN.
