I was doing the initial configuration process as outlined in Wiki doing the Admin - Configuration - E-Mail Options area for Account set-up.

When I thought I was done I tried to return back to the set-up page and received the Warning message.

I checked the error log and it has this message:
[29-Jun-2012 16:29:22] PHP Fatal error: 1194:Table 'configuration' is marked as crashed and should be repaired :: select configuration_key as cfgKey, configuration_value as cfgValue from configuration in H:\xampp\htdocs\zenproducts\includes\classes\db\mysql\query_factory.php on line 101
I then went to the indicated document and line 101 says this:
trigger_error($this->error_number . ':' . $this->error_text . ' :: ' . $this->zf_sql, E_USER_ERROR);
Being a newbie this is a little like trying to understand Greek. How do I recover from this error?

Thank you in advance!
