when I try to start the game it'll keep going to black screen and it'll keep looping anyone know whats wrong ?

Hi, been playing Rome: Total War - Alexander shortly now, but once I finish a battle, I don't seem to be able to save a replay of it. Although the button to save the replay appears, it seems to have somewhat of a whitish color, and clicking on it doesn't enable you to actually save it. In fact, nothing seems to happen, and I haven't been able to save replays so far. Anyone knows what causes this and/or how to solve it? Made a screenshot but can't post it here it seems....

Sigh... It is a sad day in the Computer Gaming world. Rome has fallen to the Barbarians! It is no longer for sale on Steam. An anticlimactic ending with no announcements, no fanfare, as the heart and soul of Total War passes into history.

thanks

Recently upgraded from a RTX 2070 SUPER to an RX 7900XTX and tried launching this game after a while. With the RTX 2070 the game worked fine as long as I didn't tab out ever. Because if I did, it never tabbed back in correctly and was a black screen. With this new GPU it goes into a spaz mode where both by screens turn black then resize the image with parts of it being covered in black blocks (imagine like a black frame around a resized image of your screen with random black blocks sticking out instead ...
