I can't download it on the C: drive because I don't have the space. I checked all my drivers through device manager and completely reinstalled my graphics drivers. When I booted the game on Dx11 it did load into the game proper but I could not open any of the menus (inventory, systems settings, map, etc.) and I soon got an error and then an infinite loading screen when I traveled. I tried the game on Dx9 and while I did not get an error and could move to different areas and accept the MSQ, I still couldn't open any of the menus. The only menus that worked were the ones linked to objects like the Aetheryte or linked to the HUD.
