Sir,
Does the board show up in device manager for windows?
The first thing that I would try is:
1) Go to the National Instruments/MAX directory and delete the config.mxs file. (make sure MAX is closed)
2) Open the command prompt under startmenu>>programs>>accessories. Change directories to the National Instruments/MAX directory and type mxsr.exe -uconfig.mxs. This will regenerate the configuration file for MAX.
Second, I would try uninstalling FlexMotion and reinstalling it. Make sure that when reinstall motion, you install the 5.2 version of the driver.
If that doesn't work, let me know.
