I've been using Flight Simulator 2004 For nearly 7 years and never lost my brakes before. Upon coming to a complete stop in the MD-11 using the auto-brakes, I then switched the Auto-brake to the off position. When I began to taxi to the gate I noticed that my wheel brakes were not working nor was the "brake" regestering in the lower left corner of the screen. No matter what I did, there was no correcting this problem. Needless to say I had to just exit the program. I also noticed that I had to recalibrate my rudder axis since the aircraft would slowly turn slightly right requiring constant correction to the left. There was no wind and I purposely keep a small 'dead zone' on the rudder axis. I am using my Saitek X-52 and it is testing fine. This has happened every time I land so far. Anyone else have this happen? If so, any answer as to a fix?
