Hi,
I have used bitcoin core for two years. I just upgraded it to latest version 0.11 (64 bit windows 8.1) and now it does not start any more and I get an unrecoverable error. I tried to reinstall it many times and finally I cancelled both program and data folders. So now I have a fresh working bitcoin core, but without my wallet. I tried to trivially copy my wallet (which is updated on May) inside the data folder, but it does not work. I know my bitcoin addresses, but I do not have access to import keys. How can I do to recover my wallet?
Thank you
