1) Try to close your wallet.
2) Go to wallet's appdata (where it keeps local copy of a blockhain, including wallet.dat).
3) Make backup of your wallet.dat.
4) Remove folders "blocks" and "chainstate", and also banlist.dat.
5) Start your wallet. It would sync with recent network state and everything would go smooth from now.
