This would be caused by the configuration group id not being set correctly for the ReCaptcha menu. When you click on the link and look at the url you will notice something like configuration.php?gID=12. Somehow the module must have registered the wrong group id. To find the correct id for the menu, you can use the query:
Use the Install SQL Patches menu under the tools menu to execute the query above. This should hopefully fix the menu link.
SELECT @gid := configuration_group_id FROM configuration_group WHERE configuration_group_title='reCAPTCHA' LIMIT 1;
UPDATE admin_pages SET page_params = CONCAT('gID=', @gid) WHERE language_key='BOX_TOOLS_RECAPTCHA'
