Ah yes, my designs are often known as the bane of all slicers. It works with Makerware, and you might try Slic3r. If you ask Leapfrog to make a driver for windows 8.1, they can use our slicer, which I'm helping to write. I guarantee you that one will print all my designs well. I can tell you from experience that writing a reliable slicer is a very tricky math problem.
