SG 01 idle 01.cas

:oops: I did not instaled any mods. I did not know mods exists. I just instaled Rome Total War, instaled the patch´s instaled Barbarian Invasion and Alexander.
BI and Alexander work just fine. The original Rome gives me error. Says he cant find DATA/ANIMATIONS/SG 01 IDLE 01.cas. What gives?
I have uninstaled everything and sis it again. Same thing. What ca i do? I just whant to play the original ROME TOTAL WAR, no mods no nothing. What can i do?
Thanks in advance and sorry for my bad english.

Probably becaused you'd patched RTW before installing BI, did you patch BI to 1.6 yet? If not try that, otherwise, uninstall everything, then install RTW, install BI, patch to 1.6 (this patches RTW to 1.5), and finally install Alexander.
