I got the same problem with the brakes after using auto-brakes. Can't move forward untill I use the parkingbrake. Then the normal brakes will not working.

Having no brakes after landing 800-WL, no matter how many times I tap the brakes key.

Maybe you guys should try and pause FSX right before you land, hit the Esc key, wait a few seconds, then click "continue flight" and the brakes should work. Sounds weird but it works for me at least. Regards,Milo Hamilton

Listen! Press your toe brakes ALL the way down at the same time and it WILL de-activate auto-brakes.
