Good ones!
3. Are you sure you have the firmware for your model? The K-1 and K-1 II have different firmware.
4. If you download repeatedly, the Mac will add characters to the file name which confuses the camera. Delete ALL of the copies or ensure that the copy you use is stripped of this extra text.
5. Make sure the file is in the top-level of the card's directory, not inside the DCIM folder or any other folder.
Good luck!
