Cant log into game anymore

Im logged into my Kingdom Come acc as i type this. I click start game and i am getting this error
Error has occured while validating access:
“Exception has been thrown by the target of an invocation”

i changed my password on my acc and i have a new video GFX card other than that nothing i have done is different. Game just wont let me logon

Was it possible to login before?

Yes i have played about ten hours of the pledged demo…saved game files…Then i bought a GTX 1060 MSI gaming x video card for a better experience, but now i cant log into the game.

Thats very strange. Can you link a DxDiag file to the forum please? You can attach it to a forum post, if you click this button.
