I am trying to run the Sensor Toolbox with the MAG3110 daughter card. When I select the "eCompass" tab, I get an unhandled exception - "Could not load file or assembly 'National Instruments.Common.Version=220.127.116.11 ...'. I've attached an image of the full error message. I've tried this on two separate machines and get the same error. The first is running Windows 7 Professional 64bit Service Pack 1. The second is Windows XP 32bit Service Pack 3. Any help would be appreciated. Thank you.
