Why Can't I See A Catalog?
Firstly, you should check to ensure your browser is running a recent-enough release to allow you to see the content inside. The supported browser editions are below:
Internet Explorer 7 and above (although we strongly recommend version 8 onwards for security and appearance reasons). We also support Safari 4.0+, Firefox 2.0 or later and all versions of Chrome.
In addition to this, you must have Adobe 8 Reader/Professional or later to be able to display most content within the catalog.
If this is all fine, it's likely that the catalog hasn't been 'published' yet and you will need to either wait for the declared release date or contact your catalog admin to request they publish it.
