As the title so bluntly puts it, I've just dowloaded the installer+preorder DLC item installers from the GoG website; the game installation ran smoothly and the game itself seems to play just fine. However, the portraits on the caracter creation menu are unavaliable (as marked by a big red question mark on the profile square) in all races and both genders.
I have uninstalled the game and done a new installation from scratch on a different location in the same drive (to discard privileges problems), but the issue still persists.
The art folder containing the subfolder portraits appears to be in perfect conditions as I can see all of them with my browser. Here are some screencaps of the issue.
I hope this is enough information to get a clear and swift solution out of this.
Thank you in advance for your help.
