In addition to the good advice already given, revert back to how you trained her with the crate in the first place. Give a treat while going in, lots of praise, etc.
My dog recently went through the phase of not wanting to go into her crate. She was so funny, taking the longest way around the house to her crate, sniffing around, stretching, pretending to see something outside... :laugh: So we started up on the treats again and now she zoomes in as soon as we give the command.
