Help with first foster dog?

I'm currently fostering a 6-9month-old shepherd mix for a little over two weeks now. Her biggest issue is that she cries every night when I put her in the crate. Everyone ignores her while she's crying, but during the day I've been training her to have a positive association with the crate with treats. Hasn't worked. I gave her a frozen-peanut butter-stuffed kong to keep busy. Didn't work. I gave her a raw meaty bone, still cried. I put toys in there also, but that's another issue. I bought an assortment of different toys (Nylabone, treat ball, sqeauky toys, etc) and she doesn't wanna play with any of them. I don't think she "gets" them. I demonstrated in front of her with my dog what she's suppose to do with them, but she still hasn't wanted to play. She also chews things up & I've been trying to re-direct her chewing to the toys, but she just stares at the toy like "what's that for?" Anyone have any pearls of wisdom? Training advice? Anything to offer in help
