It sounds like something is wrong during the loading. Like some setting or something like that isn't right for that level and because of which, you're pretty much stuck till you fix the problem, or use some kind of cheat to unlock all the levels.
Ummm, does the game have a support website? I would try to look it up first and maybe try to reinstall the game to see if that fixes the problem.
