It does that a lot even on Mavericks, I think it's just Adobe being Adobe as usual. Go to Activity Monitor and Force Quit the process called "Creative Cloud" or something like that. Then start Creative Cloud again, repeat about 5 times and it should work eventually. Then update your apps and make sure that Creative Cloud does NOT start automatically with your system. You only need it to update, it doesn't need to be running and spinning there all the time.
