As I mentioned previously, ACM doesn't work when the latest versions of modules and v1.0.1 template are installed on a fresh copy of Joomla. Change the template to v1.0.0 and ACM works.
Additionally, v1.0.1 is missing the /templates/ja_space/acm folder. Copy that folder from v1.0.0 or the new Quickstart and ACM works.
Therefore, there is a difference between template versions 1.0.0 and 1.0.1 which stops ACM working. Specifically, the /templates/ja_space/acm folder is included in the v1.0.1 download, but is missing in the templateDetails.xml, meaning it isn't copied into Joomla during installation of the download.
