The Xpen is probably the best, quickest idea. But if you still want to crate train your dog, find out if the previous crate was a wire or platic. Get the opposite. Get a larger crate. Susan Garrett has some great suggestions in her Crate Games video. She advises, for crate phobic dogs, start by using the plastic tray (wire crate) or the bottom 1/2 of the crate for plastic crates. Use your clicker or marker word and treat for any interaction with the tray/half crate. So first you reward looking at it, then moving toward it, then one foot, then two feet, etc. Take breaks in your training session and keep it fun. Use really, really good rewards (liverwurst, meatball, roast beef, etc) for this. Then start moving the tray into the crate or put the top on w/o the door. Eventually the dog should go into the crate and you can close the door while rewarding heavily.
You also may want to consider a DAP diffuser while you are retraining behaviors. Especially if your pup has some anxiety related or not related to the crate. It may or may not help, but certainly won't hurt.
