Hope somebody can help me resolve this issue. A month ago I began to use Creative Cloud as a trial mode. Two days ago I bought a Creative Cloud licesnce. Since that a message "Coluld not complete the levels command because of a program error" start to appear every time I use any command (Levels, HUE, etc.) and I can not work with Photoshop anymore.
Did it work well with trial? It is same program as you bought.
When you bought the licence did you just enter serial number into trial, or install another copy? If the latter unistall the trial.
Yes, I did not uninstall the trial. The windows that remember me how many day remaining to finish the trial disappeared. I use InDesing and Illustrator as well and I have had no problems with them. I'm usin an iMac 27" last generation With Maveric.
