Hi Everyone,let me first say what a great plane this is, and what a pleasure it is to fly....however, since going to fs2004 I have a new problem, even with service pack 1 installed. Everytime I use the autopilot or even just the auto throttle, my usb devices go haywire, including my cougar joystick. Then the sim, and my pc, usually hang. After sp1 the frame rates are fine, and it flies wonderfully well by hand, but with no autopilot I have a problem....hope you can help,antspecathlon 2600NP7-s motherboard, 1 gb DDR 400nvidia ti 4600 graphics cardhotas cougar joystickch pro pedalswindows xp (fresh install, all updates installed)fs2004

Can you please tell us a couple things?a) Have you got a latest FSUIPC for FS2004? Is it registered?:( Can you describe more in detail what "my usb devices go haywire" means We're not sure we can make a USB device go haywire. ;-)Thanks,

Hi, I think I have fixed the problem, or at least found it! I have disconnected all my goflight modules and the problem seems to have gone too. I can only assume that the go flight modules will interfere with the sim in some way. I have fsuipc installed, but have not registered it yet.cheersant
