I have been playing around with this plug-in for CS2 and when I try to process images I get the following error message. "Could not complete tone mapper command because of a problem with the filter module interface." I'm using windows xp and converting to 16 bit mode. I've also tried it under Windows 2K and the same error message appears only occasionaly on random images. Not sure if the problem is with PS or the Plug in. Anyone seen this message before? Neither Adobe nor Photomatrix have anything in their knowlege database.
