I upgraded from CS5 to CS6 for my IMac. I downloaded CS6 put in my serial number and it worked fine for a number of weeks. Suddenly, when I went to use it it said it was a trial version. I had to register it to use my CS6 I registered it and it worked, but only as a trial version of CS6 Extended. I do not want CS6 Extended. I deleted it from my hard drive and once again downloaded my upgrade of CS6 again with my serial number and it worked fine for a couple of weeks. Today, once again, it tells me it is a trial version and will not load unless I register the trial version. What the heck is going on? This is crazy. I simply want to use CS6, for which I paid. Help!
