About a week ago the Adobe Update program notified me that there were updates available. I knew that Camera Raw 7.3 had been released, so I let it run and install the updates. Since I've mostly been using LR these days, I never got back into Photoshop until today. It took an unusually long time to open, and when it did I was presented with a window that said my Photoshop EXTENDED trial had 0 more days until expiration -- did I want to buy a license?
WTF?! Apparently the Update overwrote my existing installation. The "Help/About..." window says that I'm using Photoshop CS6 Extended Trial version, instead of Photoshop CS6 Standard that I've been using for months. I closed the program to see if Adobe had a bulletin about -- no luck. Now I can't get into Photoshop without entering a serial number. Now I have a serial number for the standard version but even if this works, does this count against my activation limit?
I tried "Chatting" with an Adobe agent, but he said it was a "Tech" issue -- not in his area of expertise -- and those guys don't work weekends, so very sorry. It's likely that I'll be unable to access PS until after Christmas.
I had trouble with the same update for Lightroom. The exe. file didn't do anything when I tried to run it. I found the answer here on the Lightroom Q & A section.
Never had trouble with that Adobe Update window before, but I figured I'd pass the warning to be careful about what it's actually doing.
