So i downloaded Photoshop before and it was a trial version. I had too restore my PC (for another reason that has nothing to do with creative cloud or Photoshop) to a date when I didn't have creative cloud or Photoshop. So once I tried getting creative cloud again, I got to the part where it says launching creative cloud and it just closed and it never opened creative cloud
