I'd bet that Anthony has it right...the disc is stuck to the flywheel, and his method (long screwdriver) would likely be best way to break the bond. If all else fails, push it around so you have a clear shot ahead of you, start the thing in gear and accelerate with the clutch pedal pushed in...it should break it loose right away. If not, keep the clutch pedal depressed and go full throttle/back off/full throttle a few times. Best done in a higher gear if you have enough clear road w/no stops.
