MAMEWorld Forums - Hardware - AimTrak help for a frustrated newbie please

Hi All

This is my first post on your wonderful forum so I hope this is in the right place.Please dont hurt me too much.Apologies if not posted in the right place - I did post in more specific area but didnt get any replies..............and I am a DESPERATE mam!

I am Currently building controls for my first cabinet (an old information kiosk) and have brought an AIMTRAK.It works great with some games (american laser games,most namco games and Carnevil!) but I am having problems with others.I do understand the basics re gun callibration and in mame callibration so I have tried lol.On Operation Wolf the crosshair WILL NOT move in the left portion of the screen no matter what I try.It is like there is an invisible barrier across the screen.I have noticed now that a lot of games seem to have parts of the screen that the crosshair just wont go to even if I calibrate gun in game.
The other 2 games I am having probs with are Terminator 2 and Alien 3.I understand that these are "positional" gun games and have read up on forums about callibrating the x and y axis as these games arent "true" gun games but when I go into MAME config for the particular game and try to set them the gun doesnt register any movement?Please can you help me in the simplest of terms as I am a bit of a MAME controls newbie.Thanks so much and sorry for the rambling 1st post

PS - Also cant seem to get the side buttons on the aimtrak to register when callibrating in mame almost like they dont work?What should I set them to on aimtrak cal page to get them to work as I have tried everything
