Unfortunately, there is (at least currently) no savegame conversion from 0.16 to 1.0. There are several changes introduced to reduce savegame incompatibility starting from 1.0.
I could try, if you really want, to manually fix your savegame, but anyhow you'll miss all the changes made to the world, so as the new "Act 2".
I would tend to advice you to start again to play...
