I am not sure how to acquire the 'Dxdiag output'.

Thanks to your help, I was able to access the older version of the map again, both in the editor and in skirmish mode. However, when I attempted to publish the newer version of the map, only the old one displays. I can access the new map locally though. As I understand it, to update a map, I must publish the map under the same name, which I did.
