To improve security, we will soon start forcing password resets for any account that uses a weak password on the next login. If you have a weak password or a defunct email, please update it now to prevent future disruption.
If I recall, there's a text file the game references to determine what's been completed/unlocked, and if you edit that file, changing all the 0's to 1's, it should just unlock everything. I don't know if this still applies or not though, it's been many months since I played it, and that was definitely not the latest update.
