Here are some tips:
Leave the crate open (and maybe even just the bottom part for awhile) with her blanket in it and put her favoite toy and a bully stick/treat/whatever she likes in it. Kepp it where ever you spend most of the day with her (in the living room or where ever) and let her get used to it. Then you can add the top and door.
Also you should try feeding her in the crate. When it's feeding time put her bowl in there. This will teach her that the crate=good things.
Also you can put *very* tastey treats under her blankets (when she's not looking) so that she gets something special "from her crate."
Also, if possible, don't take her out when she is crying...this will teach her that if she cries you will let her out. Sometimes just letting her see you will make her stop crying and then you can say "good girl" and let her out.
Best of luck!
