[2022] First the game began to crash. I uninstalled it and now cannot seem to be able to re download it.

Hello, my downloaded version of Anno 1800 has been working fine for a couple of years now. Two day back it froze and then crashed with a window stating an unexpected direct x failure. I tried to open up the game again, nothing but a black screen with a box indicating "Failed to create the Direct 3D device. Error code 1205. I rebooted my computer. The game launched just fine but after 10 minutes it froze then crashed. It also seemed to affect the launching of my other games on Steam. When I rebooted the computer again. All the games worked fine. Tried Anno 1800 again, 10 minutes in and freeze and crash. I thought perhaps a clean install so I uninstalled the game but now cannot for the life of me figure out how to re download it through Ubisoft's site. Ummmm....Help??
