Collectible Card Game Headquarters

Hi guys,
here I have a strange behaviour of the program during an online game.
I'm using version 1.5.56, my friend too. We are using Teamviewer VPN to play from our home, connection is fine. On my side everything is good. I'm also the server of the game, his only a "client". When he draws his opening hand, a pop up appears showing this:

He doesn't see anymore pics of the cards, and some cards are foil (randomly......this is MY setting however, very strange). One thing that can help: our settings are very different (local directories most of all)....maybe this is the problem? When he doesn't play online he sees no problems.
Thanks to everyone who will help!!
