I use Windows 8 with i7, 8 GB RAM, and 2 GB Nvidia graphic card.
Around 12 hours ago I subscribe to Photoshop CC and Lightroom 5.
First I downloaded Lightroom 5 and installed it. It is working smoothly with no issues.
After that I installed Photoshop via Adobe Creative Cloud for PC. After installing Photoshop, Photoshop kept on crashing whenever I open it. Then I signed out from Adobe Creative Cloud for desktop restarted my PC thought that it would solve my problem. After restarting my PC, I cannot log in to Creative Cloud for desktop. Whenever I try to log in, it logs me in for 1-2 seconds and then automatically logs me out. Add on, Photoshop is asking for a serial number. Please note that my Lightroom is still working smoothly.
