I'm using Joomla 3.4.1 and CiviCRM 4.6.2.
When I click on Mailings > New Mailing, it's as if the component only partially loads. I have a menu bar with Search, Contacts, and Contributions; no other menu options. Below, I simply have the print icon and the version footer.
Is there a way to reinstall just the CiviMail component? I'm not an advanced user, so I don't even know where to start in trying to find out what's going on.
