...Not sure I understand what you are trying to do, if you are using the mod under the impression that the ACE functionality is intact - it is not, it's been modified to suit purposes of the development... If you are using ACE alongside the mod, well... There would likely be conflicts, as this is a total conversion. However it probably doesn't matter... I was told a while ago that ACE will be cut out of the mod at ACE Team's request. Possibly to be replaced by some other modified version of AGM... I believe at one point there was an older version left in the public realm.

What I am trying to do is make my own scenario to try some things but whenever you start it and try to do any ACE3 action by pressing the windows key, it just doesn't open which totally breaks ACRE2 for instance as well.
