Hiya,
If your hosting Cpanel has phpmyadmin installed, you can go in and delete it from there.
If you cannot do that try this.
open the modules xoops_version.php and look for the lines with the database tables and comment them out and install the module again. Once it is installed, uncomment those lines and then uninstall the module. Once you have done that you should be able to install the module properly.
