Thats exactly what I just did.....
I recommend the following steps:
1.backup your FPS directory - best onto another drive.
2.then uninstall the game and the patches
3.THEN delete everything inside the directory
4.Install the game and the 1.09 patch
5.Ad the airmode scripts according to the readme and overwrite your game.exe with the one from airmod (personally I used S4ModV2)
6.And then choose ONE WEAPON and modify the gunspec - only one!
7. build a simple 2 (large) rooms game with 1 enemy whos main script is people/strafe
8. Now play the game and see if your weapon behaves like it should and like you want it too. the strafing enemy will show you if your ironsight setting is too slow (p.e.)
If you want to edit the gunspecs DONT return to the editor. just edit the gunspecs in the the mygame(or whatever)/gamecore/guns folder and play the game again. do this until you are satisfied with your weapon.
I recommend to reinstall all your weapon packs (and anything associated like hands etc.) first and check one (airmod-supported)weapon from each if everything works. After that reinstall the rest
