CTD in loading screen when entering battle (RBAI installed)

[Freezer]

Hi,

I recently decided to reinstall Stainless Steel. However, every time I enter a battle I crash. Kingdoms version is 1.5, SS 6.4, OS is win 7 and no sub-mods except RBAI. I guess I should also say that I played a battle an hour or so before this problem occured, so this is definately a problem that is new. I'd post the logs, but when I look in my /logs folder it's empty. I assume it contains vital information to solve my problem, so if anyone know how to fix that it would be great. I've googled the issue, and this is what I have tried:

- Installed RBAI and enabled it in the launcher
- Reinstalled both 6.4 and 6.3 with admin rights.
- Launched the game with admin rights
- Downloaded Hospitaller fix (no hospitallers in the battle though).

If anyone has a solution to the problem, that would be awesome.

EDIT: Found a system.log .txt file in \Medieval II Total War\mods\SS6.3. Not sure if it is of much use though:
