I'm trying to review my flight data with Assistant 2.  My Mavic connects OK.  I've updated the firmware without any problems, but I get nothing but blank screens when I try to view my flight data.  My Win 10 Device Manager tells me:
Device USB\VID_2CA3&PID_001F&MI_04\6&30171864&0&0004 requires further installation.
Ideas:
Thanks

Could you please provide a screenshot of the blank screen?
Totally blank or cannot shows the graph?
