extra levels won't work

I have all the artifacts and parcels and the three extra levels seem to be there but I cant go into them. I'm trying to get 100% and I've done everything else I can possibly do but those three levels won't work at all. Am I stuck ? Is it a glitch ? Do I have to start the whole game over again from scratch ? What do I do ?
