Start Spartan Campaign / CTD

[grajunior]

Hi, I am using Win7/64bit, 8 GIG Ram, and a ATI Radeon HD5870.

My Problem :

Play RS2 with Rome/BI. Followed the install instructions exactly (seperate Folder and so on...).
Then starting the Roman Singleplayer Campaign (not 1 Turn) and it works fine. Now I want to try the Spartan Campaign. The Campaign Options Window opens (Battle Difficulty, Manage Villages, Advisor......). Than pressing the Button "Start the Spartan Campaign" at the Bottom of this Window - Then a Scrolltext tells me the Story...and when I press the Arrow in the lower right to start the campaign, I got a CTD with the Windows Message : "Rome Babarian Invasion has Problem an is shut down - Searching for a Solution of that Prob."

Hmmm, got now Idea whats wrong. Need your advise.
Thaks a lot and sry for this cruel English.
