I have "successfully" upgraded, but when I try to go to the zencart admin (http://...admin/index.php I now get this error:

Code:
1146 Table 'aap_zencart.zen_project_version' doesn't exist
in:
[select * from zen_project_version WHERE project_version_key = 'Zen-Cart Database' ]
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 can it mean?
