Mach1 Question?????

I cant save the sets from the configuration

I installed Mach1, but I can't set the pin configuration, if I open
Printer Port Output Pins Tab and set the pins, then go to Input
Signals Tab and set the limits and activation, if I go back to Port
Output the changes where not saved and so on.
If I try to move the motors, they do not move but nether the DROs.

Does somebody knows what's happening?

Best regards
