I have been using Trello very regularly. Last week I clicked to enter and a screen said there was no account with my email. I entered the correct one as I made a note of the name (email) and password. Login failed. I emailed the problem to Trello and got a confirmation they don't have an account with my address. They must surely keep a backup of accounts , but have offered nothing. Does this mean there is no backup? The pages have a lot of vital info which I thought was 100% safe. And I never noticed if there was a backup button which would put it on my hard drive. This is serious for me and I'd be very grateful for suggestions. Thanks
