It says the program is compatibility with psd, tiff, and jpg files. Do these files have to be 8 bit only or will it take 16 bit files?
8 bit only, and no extra complicated stuff - no adjustment layers, no editable text, no nested layer groups (groups inside of groups), no clipping layers; I don't remember if painter essentials supports layer masking, but it's safer to avoid those as well for stability and performance reasons.
hope this helps!
Thanks for your reply. That was the only file format that i could get to work. Interesting that it doesn't tell you this anywhere i looked.
