Could not configure the app - OS X issue

Dear support team,

i cant open freedome vpn sw on my macbook pro // OS X Sierra

im getting strange error

Could not configure the app. Restart Freedome and try again.

i bought one year subscription two days ago based on recommendation of my friend working it security business.

ipad and iphone app works well, also my two windows machines.

Unfortunately the most important computer - macbook pro - doesnt.

I thought that this could be router issue, but my windows laptop is doing well and freedome is working.

vpn app on iphone is also connected in few seconds on this router.

thanks for any advice.

Br

Peter
