FOCKE WULF -8 FIRE PROBLEM

HI MI LIVING IN MEXICO, AND SOME MONTS AGO Y BUY THE CF3, MI PC DO NOT HAVE A VIDEO CARD BUT THE GAME WORKS WELL , OF COURSE ELIMINATING SOME VIRTUAL EFECTS.
OK, WHEN I FLY THE FOKE WULF WHIT EXTRA 30MM MACHINE GUNS, THIS PAIR OF GUNS OPEN FIRE HMSELF, WITH OUT PUSHING ANY BUTTON, ITS NOT A JOSTIK PROBLEM, THEY FIRE AND DO NOT STOP UNTIL I SIGHT THE TARGET AND FIRE IT, AT LAST THEY STOP FIRING AND THIS WILL NOT HAPEN AGAIN DURING THE GAME , UNTIL Y STAR A NEW GAME, I TING THIS MAIBE HAD SOMTETHING RELATINED WHIT THE MODALITI OF BOMBER ANDA IS EXTRA GUNS THAT OPEN FIRE AUTOMATCALLY . AS I SAY I LIVE INMEXICO ANDA I MY CITY THEY ARE NOT CSF LOVERS, ALSO WHEN I TRY TO PAINT THE PLANE SOME OPTIONS I SELECTED DIDNT WORK ,THE PAINT IN THE FRONT THE SPINERS ADNA THE TAIL DIDNT WORK,
