Were there any database modifications that the add-on required you to make, but you didn't?

That error means it's looking for a table in a database, but that table isn't there.

Looks like, if you tried to uninstall the add-on, that some or all files of the add-on are still in place on your site and looking for that table. Otherwise, if you've installed the mod but not uninstalled it, you didn't make the necessary adjustments to your database when installing the add-on.
