Just a follow up-the restart did not work.
Also, I uninstalled the game, but left out the save file.
Reinstalled the game, put the save file back in the save folder.
Same thing happened.
Black screen when attempting to start the campaign. Just to clarify even more, this did not happen for the first 11 campaigns of the orc campaign in TOD.
I attempted to just begin the human campaign and the same thing happened, so it would not even let me begin that campaign.
I downloaded the game file off of this website to try that out, but also no solution
