Ok, so I crapped my pants when I saw that RSII was out.
I downloaded the torrent with the three 6 parts in it. I then uninstalled RTW, and deleted the whole Rome Total War folder to get rid of RS1 (oh the pain).
I then reinstalled RTW (its the gold editon so no need to patch, don't have alex either) and then ran the RSII_setup exe.
It then installed fine.
I go to boot it up and I get a black screen and then nothing.
Is there a log file that gets created when this happens that I can post here?
