Paint Kit Request for Help with Paint Shop Pro

Hello All,I downloaded the MD-11 paintkit this past weekend in hopes to maybe make some of my own edits. I see that on the PMDG website these files say they are compatible with Jasc Paint Shop Pro. I'm a Paint Shop Pro 8 user myself and it has met all of my image projects in the past, FS and otherwise (have never really had the need or cash to purchase Adobe PhotoShop). When I open the various paint kit files with Paint Shop Pro v8.1, I receive an error saying "The PSD file contains unsupported features." While the file does indeed open and looks as I'd expect it, it looks like the layers become lost, leaving simply the aircraft on a "background" image. This makes it difficult to paint while keep the nice rivet, dirt, and other effects. Is there a chance of getting a .psp version of the paint kit rather than .psd (I think this would keep layers in tact for PSP users)?Thanks!
