Your log report is at least a bit strange. Check your log file in the Medieval II/logs folder. I really think it is due to a wrong install. Try reinstalling. If you use Steam or if you use Win 7, just let me know.
It seems like you can post here, try simply typing here what bugs you have found
Did you manage to start the game or do you have a crash upon start? A bit more detailed crash description should be helpful...
