Wow, update on those store shelves and floor drawing, I can't open it for some reason. When I made it, I copy pasted lots of shelves of goods, as well as the floor, and after printing it I saved it. Now it's a 130MB file that I can't open, but I can see the thumbnail.
Too many bitmap objects in a CorelDraw file can corrupt it, I'm afraid. You might try importing it into a Word document (yes, that's right) and see what it does...
