I have been having trouble with my MK3 stopping in the middle of a project. I replaced the driver board and still having a problem. After downloading the latest software and firmware (2.10.1112.1601 HW 2011.11.14). I tried to import the latest settings from phlatboyz and it will not import. Mark helpled via teamviewer, manually entered the correct settings. I still have the same problem and some of the areas in the settings are greyed out. I uninstalled the software and drivers and reinstalled, still will not import settings and have the same problem when trying to cut. Running Windows 7 Home Premium.
