Sounds like you dried and skipped the curing step. Not to worry, you can re-hydrate your bud. Here's how:
Put your crispy bud in a large sealable container. A Tupperware bowl w/lid or large glass jar are both good. Cut down a solo cup so it is just 2 to 3 inches tall. Take a paper towel and fold it so it fits into the solo cup and add enough water to soak the paper towel. Set the cup inside the container straight up to make sure it doesn't touch any of the bud. Seal the container and check every 4 hours or so. Reefer re-hydrates a lot faster than it dries so you have to check your container early and often.
Good luck, BigSteve.
