Webform content not getting saved to database; not receiving emails.

My site is in Drupal 5.7 and have converted all my surveys to webforms using the survey_webform_migrate module. I have a webform with several form components. All form components have the "E-mail" box checked, and I have my own email address in the "Email to" field, yet I am not receiving any emails when I submit the webform. Also, when I look at the webform_submitted_data table using MySQLadmin, I can see that data from only one field is being saved to the database (my webform has 5 fields).
Has anyone else experienced either of these problems with webforms?
