I had an older wallet version, now I'm trying to insert the wallet.dat in new folder wallet v 1.1.0.0 .. "error" ....why?
Dev solution?
Come join us on Slack. You need to dump and import your privkeys into a new 1.1.0.0 generated wallet, or create a new 1.1.0.0 wallet and send all your coins to the new address.
