I may have found the reason for why the game changes to a black screen for me but it doesn't explain much(For me anyways, if any of you know I appreciate any help). I have task manager opened and the game was using around 15% of my cpu for a while, and when it turns black it goes straight to single digits mostly below 5% I'm not sure why this is happening since every other game works fine. It's just this one that's causing problems.
I'm afraid no idea why that might be happening. Maybe antivirus? Or maybe you have a corrupted version or no version of RPGX (I think that's how it's called)
The game runs in RPG, I think this is the one I have, I think, maybe if you never installed it?
Aside from that, i can only imagine your antivirus might be breaking the game, or the game you are downloading is corrupted, try a different version, I first used a non translated version.
PS sorry for the delay, I don't visit this thread no more, and I am also not an expert, just brainstorming ideas that broke my games in the past.
