Blank Page with Message: Armadillo Problem

I’m having a problem with Armadillo. As far as I can tell I’ve entered all the database details correctly into the Stacks. This is my fourth MySQL database. Instead of the Stacks page containing my Armadillo blog I’m getting a completely blank page with this message only (username blanked here):

There was a problem fetching a list of posts from the database: Table ‘d**********.armadillo_post’ doesn’t exist

Thanks for any clarification of what this means?
