Incorrect key file for table 'smf_members'; try to repair it

My forum shows the message above now and I can't get to the forum.

Any ideas?

You need to use a tool like phpMyAdmin available through your hosting control panel to repair the table.  If you're unsure of how to do this or access it, you might want to open up a support ticket with your host.
