Since we are having issues finding a place to host the MP version of the game here are instructions on how to convert the SP to MP on your own.
Instruction
1) Go to the SuperAIBundle folder and highlight everything in it.
2) Hit CTRL-C with everything highlighted.
3) Go to the Hearts of Iron main folder
4) Hit CTRL-V and when asked to overwrite files say yes
5) To run the game, run the HoI.exe file directly instead of the Icon for Super AI Bundle
Thats it you are then ready for MP!
