If you are sure that this is the case, then it can't be something with Admin Tools. Admin Tools only allows you to create a .htaccess (which could block the component) and enable various WAF settings (which could also block the component). The former should throw 403 errors, the latter should trigger an exception in the log. If nothing of those happens, it's not related to Admin Tools.
Can you give me an affected URL so that I can take a look myself?
