This is s bit of a concern. Does it still say 221? You may need to reset. There are instructions on how to do so here at the MultiBit help page:

Do you have the transactionID? If so, you can search for the transaction at the blockchain.info website. Use the search box here:
https://blockchain.info/
If blockchain.info displays that the transaction is unconfirmed, then the sender probably didn't include a sufficient transaction fee. It could take a few days (or weeks) for it to be confirmed.
If blockchain.info displays that the transaction is confirmed, then you just need to get your MultiBit wallet synchronized with the blockchain.
