Lost all my cards!

Anki Help
1

Hi,

I downloaded the new update yesterday onto my Mac. Went fine.

When I now go to open Anki, it is saying its unable to open my collection file. I logged onto Anki web, and my decks have not updated so I’ve lost three months work!

Could anyone please help

The manual has a section on how to recover automatic backups, maybe this could help.
