I have purchased several bundles of actions from a couple of companies and some of their actions require "invert" as part of the action. My CS5 will not allow invert and gives me the error "invert command is not currently available". Obviously the action cannot be run correctly without the invert command. I have Windows 7 and am running CS5 64 bit extended. I have tried unlocking the background photo, I have also tried to make a working copy of the photo, to no avail. Any help would be greatly appreciated.
