as I understand for a full recovery of my purse I have:
1. To clear all the information in appdata\loco
2. Throw the downloaded blockchain
3. Start and wait for full synchronization
4. in the debug console write importprivkey XXXX
5. Wait ....
In step 4 I would recommend copy in an older backup wallet.dat that contains all your addresses. If you decide to import private keys make sure you import all your private keys. It is good practice to make a backup of your wallet immediately after creating it and everytime after you add a new address to the wallet.
