Error - Historical Battles not working

[Capricornius]

I didn't get any replies on another forum so i thought i post it here:

I have this weird problem that occurred when I tried to play historical battles. I clicked on the battle i wanted to play and then i went and clicked the arrow to start playing. The game then immediately sends me back to the area where i choose the battles. I tried again but this time it wont even let me get past the first part!
I kept trying this but no matter what battle i choose, the same thing always happened.

-BTW, when i exited the game, an error message popped up: it said - DATABASE_TABLE error found: unrecognized record id poeni infantry request (THIS only happens when i exit after experiencing the problem with the historical battles).

Any help would be much appreciated!

I believe historical battles weren't adapted to RTR and its submods (ExRM, for instance) and the game tries to put vanilla troops in the battle, hence the error. AFAIK only Magnesia works, because it was used in the RTR intro video.
