Wallet Error Message - on Wallet Load

Previously I was using Peer Unity and have switched over to the Peercoin QT and now receive the error message below when loading up the wallet.

“Warning: error reading wallet.dat! All keys read correctly, but transaction data or address book entries might be missing or incorrect.”

1.Export private key from Peer Unity and import in QT…
2.In Peercoin QT you need to redownload blockchain
