Need help

I downloaded rdr2 from fitgirl and I encountered two problems.After doing everything from limiting ram during installation to increasing paging file size there are always 3 corrupted or files that aren't working.I tried ignoring that fact after trying everything and after launching the game from the cracked launcher I get a black screen that just lasts forever and for some reason it doesn't allow me to even go to fullscreen.

Note:When I open the game I do see the white bar at the very start.Once it's completed the screen just stays black.
