I have a Megatouch Ion and got an upgrade kit to the latest 2014 software for the machine. The memory stick that came with the hard drive, believed to be 512K, allows me to calibrate the screens but doesn't allow me to see the upgraded software, only the older games show up. I tried both a PC2100 512K and 1GB memory stick but the system won't let me calibrate at 1024, the image for the calibration screen is off center. If I skip past that process I do see the upgraded software but of course none of the new games work as the screen isn't properly calibrated. Any thoughts?
