I use navigraph navdata center 1.0.7
After logged in, I pressed the install button, it shows installing. after a while popup a warning says downloader.
Today,I reinstall my windows and the sim, and use the clash to insure the net connect.
I still get this downloader warning, anyone can help?
Hi.
As a test, please disconnect any vpn’s or Antivirus which might cause timeouts on your internet connection to Navigraph.

Hi, lan.
Turned off the Antivirus and the firewall&vpns, still get this warning. I also noticed the network usage and data received in a very small figures.
Please see the pic below，thank you.
My mobile phone hotspot works this out, its a network issue.
That was my next suggestion 
Hope you can sort the network issue.
