Does she have a blanket to snuggle with? How long ago did you get her? If she's a new arrival, it might help if she has a blanket that smells like her mother and siblings, since she's been with them all her life. If she's been with you a while, you can give her soemthing that smells like you. A blanket or old t-shirt will do. Sleep with it for a few nights, and give it to her.
If that doesn't do the trick, you can either let her sleep in bed with you (and be prepared to let her sleep with you every night for the rest of her life) or you can ignore her and she will eventually settle down. If the crate is close enough to your bed, you may be able to put your fingers through the bars and let her sniff them, or pet her if possible.
