Active Camera has forgotten how to use itself...

Hey Fellas.For a long while I've been using Active Camera for FS2004, but since the beginning of last week, whenever I try to use it's lovely features, they don't work. It's as if it's erased all the control assignments. I've tried re-entering them, but I've come across 3 problems in the process.1 - I can't re-enter the control assignment for using the mousewheel to look around.2 - When I re-start the sim, they are erased again.3 - The control inputs are very dodgy. For example, if I re-enter the sidestep command, and tap the button, it'll keep moving on it's own!I was wondering if any of you guys would be able to help me out. I think I have Active Cam V2, if that's any help (you know what it's like, there's so many different versions it's hard to tell which one you have!). I Don't know anything else....Help is much appreciated, thanks guys
