Photoshop no longer starting up
I went to open up Photoshop today to work on some images, but instead of the program starting, a Creative Cloud Photography screen popped up stating "Validating license online" then flashes to another screen that says "Please wait for a moment..." and then it just stays there spinning. I don't even use CC. What could be the problem? The Photoshop program worked fine a few weeks ago and I've done nothing new to the PC or anything. Thanks in advance.
