2 to 3 weeks isn't so bad. some people were predicting never! the patch has to be changed to deal with each version, i am guessing that kind of thing isn't as straight forward as you think.
Figured it out. In the folder:
F:\Program Files\Steam\steamapps\common\iron warriors
I renamed the file start.bat to start2.bat, and renamed the file startwovid.bat to start.bat.
Now it starts!
I can't run the game, it pops up a DOS box then exits:
"Problem checking Steam Application"
I have logged a call with Steam support, but I suspect they won't be much help. Anyone else seen this? I tried reinstalling.
