i asked a couple of guys about this, sent a pm to them On BIS fourms.
i swear the arma.rpt is nowhere, i did a search of my 2 harddrives and it dotn find anything, i even made the hidden folders viewable and looked based ont eh path, tis no where to be found.
I have windows XP.
However, I think you need to look into alternatives to UserAction. I've learned that it can overwrite other custom user actions (added from other addons). It should probably be called using CBA Extended Eventhandlers.i really dont know what would work all this is beyond me, i liked the way it was working but if you know of another then thats cool.
