This is not an issue with Admin Tools but with a third party plugin which is attempting to hijack a core Joomla! API called JDispatcher, used to run plugins. We regret to inform you that we cannot provide support for third party code.

My advice is to try disabling system plugins one by one until you find which one is causing the problem.
