Hi again Niels!
I finally managed to establish a connection! 🙂 I don´t know if this time it worked for no particular reason or if it was due to some changes I did in my firewall settings *hehe*. If any other forum member encounters the same problem and till yet couldn´t connect to the server it might be that the firewall of your anti-virus software on your pc – per default – blocks animationpaper from connecting with the server…so you might want to check this up.
