I get this error when trying to install Admin Profiles (I have ZenCart version 1.3.7)...

1146 Table 'magazin.zen_admin_menu_headers' doesn't exist
in:
[select id from zen_admin_menu_headers where header = 'Configuration']
If you were entering information, press the BACK button in your browser and re-check the information you had entered to be sure you left no blank fields.

What should I do?
