I can not import any schema or library. When I press Import I believe I can not connect to the server. I do not understand where I'm wrong. I'm not given any error message but it does not matter. What should I do? In version 4.6.4 I only see Altium and Eagle and I saw that in others, for example, there is LTspice or Kicad. Thanks for your help.

Hi Walter,
Please try Chrome browser.
Because the import of LTspice or Kicad is not good enough, we off line them.
thanks
