Hi Gerardo,
You should be able to see from the various module screens under the Site Administration if any modules are missing from disk. In 2.x and up there is a plugins overview repost that should show you this for all types. If any show missing from disk, this would indicate that the tables are still present in the database even though the code is no longer on the server and the schema would be an older schema if you have upgraded the site since the code was removed. If you find any of these there is a link in the manage plug-ins screen for each type to delete the plugin which will remove the tables that are causing the problems.
