Which version of the plugin did you install?
ACF has some field types which are only available as premium addons, this include the repeater field, flexible content field, the gallery fied as well as the options page.
Additionally, there are several field types such as the link which were added in later version (5.6)
Kindly be sure to use the latest version and if you do not have access to the PRO version, you may try out upgrading to the free version 5 as described here.
Hope this helps.
