bug after update?

The game updated on Steam yesterday, and now whenever I complete a dungeon I am dumped at the opening Desktop Dungeons login screen. My progress appears from the most recent run appears to have been lost, too.
I don't have a desktopdungeons.net account and don't want one.
This worked fine before the update.
What happened? How can I fix it?
Thanks.
