Hello,
I have had a serious problem today, I started backing up the MySQL database within the admin section of zen-cart using the database backup contribution. It seemed to stall part way through, and then my URL was no longer visible, instead i got an error complaining that there was something wrong with the zen-cart cache ... no pages showing, just the database error. My hosts rebooted the server to try and fix the database error and it appeared to work, ie I could see the site once again.

However, i have just tested a few things out and i have found that when someone trys to sign up, and the email is sent to them, the get greeted with this

1016 Can't open file: 'zen_email_archive.MYI' (errno: 144)
in:
[insert into zen_email_archive (email ........ blah blah blah ......

there is loads of stuff here, but its all text ... I hope someone can help.

Thank your for any efforts.
