Please update wallets to v2.1
Previous blocks have not been deleted all is OK .
Please delete block-chain and all other files from the Thanks appdata folder , excluding of-course the wallet.dat. Don't delete the wallet .dat or all your coins will be deleted. Once you open your new wallet just let it sync up and all your coins will appear.
