Jack, there are adjusters on the iinside of the closet doors to raise them. I had that problem with mine and ended up having to remove the carpet under the track to lower it enough to allow the doors to slide. My coach ('03) spent most of its prior years in Florida and the high humidity caused the particle board under the closet doors to expand. I was not able to adjust the adjusters high enough to allow the doors to slide without lowering the bottom track (by removing the carpet from underneath it). If your closet doors slide OK when the slide is in, I don't know what you can do to remedy your problem - other than try to adjust them as high as the adjusters will allow and see if that fixes the problem. You might also make sure that the slider slots in the bottom track are clear of any debris that could inhibit the free slide of the bottom track retainers. Hope you get the problem fixed.
