Installed CC, payed for Photoshop, downloaded the programme, did update and when I want to start working it says:" impossible to initialise PS error in the program". Deinstalled the programme and downloaded everything again: same result. I work on a recent iMac with OSX version 10.9.4 What can be the matter?
reset your preferences by holding down option/cmd/shift during pse startup. you'll see a confirmation dialog if done correctly.
