I've moved you into your own thread, as you now have a problem unrelated to the thread to "me too" posted in.
Please run DXDIAG, Save All Info, and post dxdiag.txt here (first delete everything after the Sound Devices section so it will fit). Also post your Rome/settings.txt and Rome/logs/system.log files. Note that if you use Vista and have installed the game in the suggested folder c:\Program Files\Paradox Interactive\Rome\, the active versions of these last two files will have been redirected by Vista to a non-system directory, like c:\Users\[name]\AppData\Local\VirtualStore\Program Files\Paradox Interactive\Europa Universalis - Rome\, where [name] is your Vista user name. You may have to search your C: drive for them.
