Hello everyone nice to meet you all
First of all I'm new in this sort of thing so I will ask several questions :

I have downloaded the DMM player (it is said the latest version was from October 2023 so I download that one). Successfully installed although had to wait for about 40-50 mins to load and wait a bit more for the player to launch. However, before the player launched there is an execute command and I was rather confused but I decided to click "No" then few moments later the player launched. I wonder if that execute command affecting the whole resources or not?

And so, after I have managed to access the player I saw most portraits of kamihime, eidolon and soul are missing
I have also can't open the story at all. There are also problem with the H-scenes with those who portraits are missing. How can I fix this are there bundles of those missing files or I should added them manually one by one? If it had to be done manually what should I do?

Okay that's all for now I would be glad if you all here can give some help cause honestly I'm not really good with this kind of stuff lol.
