HI everyone!!

I am new here , but I really enjoy this site!!
My issue is that I can sometimes sync and other times it starts to connect and then the button goes back to grey , saying im not connected? My x50v shows the connection thru USB, but my PC shows the grey button?
I have soft reset, and rebooted my system as well- and nothing??
Any help would be appreciated!! I have a X50v with a05 and wm2003 os!
Thanks
Rick
