Help with old civicrm tables

I am working with an organization to set up their WP site. They originally wanted to use CiviCRM (as they had in their old drupal site) but decided against it. I had installed CiviCRM and it created its usual tables. I had started to import some data from the old site when the change was decided upon. I uninstalled CiviCRM but it did not take its tables with it. However I didn’t realize this until the site setup and use had progressed.

There is data in a number of the CiviCRM tables. When I delete the CiviCRM tables through my host, many of the pages and posts disappear from the site although there are also WP tables for pages and posts which seem to be populated.

How do I 1)get the current pages and posts into WP tables rather than civicrm tables. I have installed a membership manager, but having lots of problems which I attribute to the CiviCRM mashup.

Alternatively, what would I need to export from the current site to be able to import back into a new installation of WP, to set things up properly.

It’s really a mess. I appreciate any help that can be provided.

Thanks in advance
