Query: Way Too Difficult to Mount

I bought my Continental Ultra Sport Hometrainer tire (700x23) a year and a half ago from a local bike shop. I had read reviews that said it was hard to mount, but they failed to tell the whole story. This tire is nearly impossible to get on the rim and once there, it won't seat properly. Changing tubes would take well over an hour - mount, inflate, not seated properly, delfate, remount, inflate, not seated, etc, etc, etc. Once you got it, the ride was fine and the tire was quiet. I recently replaced it with a Tacx Trainer Tyre which mounts much easier than this one. I bearly got a years worth of riding out of the Continental before it wore out.
