DXO Collection 4. I used CONTROL POINTS successfully in various plug-ins, and then SUDDENLY I could not open a control point. I tried restarting computer. That did not work. I sent a ticket to technical support.
Yesterday, I decided to upgrade to DXO Collection 5, thinking perhaps that might fix the problem. Nope. I cannot open a control point.
Any suggestions while I wait for DXO technical support?
A little more info might help. What program are you using to launch NIK and specifically which NIK app(s) are you using? Also are you editing a TIFF or JPEG?
