OK, I tried installing EB. It wanted to install in the default Activision C/programfiles/activision/rometotalwar spot. But, when i installed RTW and BI it installed in c/programfiles/thecreativeassembly instead of activision. So what i did was install it to the C/programfiles/thecreativeassembly.
But once i started regular rome total war, it started as the same, and there were no changes whatsoever to the game. please help. :(
