Im cant start the game when its loading its says File exception in diskfile.cpp line:433 Could not open file. I have FTM version 3.05 does the mod need to be patched too?
Yes, it works, but you should make a copy of the mod folder(where Dies Irae is installed) before applying the patch, so you can easily replace it in case something goes wrong.
That just means it won't work with the Common Weapons of WWII dlc or any user created mod's.
You should first get a good handling of how FTM works, after that you can check the HoI3 user modifications forum: http://forum.paradoxplaza.com/forum/forumdisplay.php?415-Hearts-of-Iron-3 (make sure you have an account and registered HoI3 first) and check what mod's you might like.
