opps, software didn't want to let me edit....
If I recall...
removal was done by unscrewing the bottom track and the "rollup chamber." Pulling back from the bottom will move it out of the top track.
IF you can get your hand on the back side of the tambour door try lifting from both sides as you push gently to open fully. It will be much easier to remove the whole thing once it's in the open position... however once open you could then just use a motel sized bar of soap to lube the tracks to see if that will work the problem out.
