Ah, I seem to have solved that problem, the folder name for the module must have an underscore in it for it to work.
But!.... Now I have the page loading ok in the CMS I have found something odd. Within the 'Albums' and 'Photos' tabs it seems to have lost its formatting, see attachments. When I add an album or photo it seems to load it in full in its own page rather than in the CMS, again screen grabs attached.
