Get the newest wallet (...96)... backup your wallet.dat... get your privkey....
start new wallet and change "roaming folder".... restore your wallet via privkey... should solve ur problems...
I downloaded this bootstrap and when I installed new Odarham wallet I searched %appdata% to open roaming file for wallet and delete chainstate and blocks and replaced with chainstate and blocks from bootstrap and put in my wallet .dat which synced it so it worked eventually.Thank you to all the useful advise from posters on the thread for pointing in right direction :-)
