David, I spoke to various players and some don't have the User file in the Steam Remote folder either. Maybe the DVD version is different to the Steam DL version but I have various Config files in the Remote folder along with the User file - my MP loadouts seem to load from the Remote User file....very strange.


I have never been able to get loadouts to work from the Weapons options menu. The only way I have ever been able to try different loadouts is by loading a mission into FMB and selecting the load out in the ac weapons ammo belt properties box. This loadout is then stored in the mission file. However, you must first have your loadouts stored in the User file which is what the OP is describing. If done correctly, whenever you use FMB you should see the weapons loadouts you created as they will have whatever names you used to identify them.
The FMB doesn't locate quick missions for edit as these are stored in a different folder but you can copy any quick mission and paste it into the Single Missions folder - you can then load it into FMB to assign a weapons loadout and also set the plane you wish to fly by ticking the checkbox as Player (found in the properties menu for that ac).

You will then see it listed as a new Single mission.
