Can't get MyRecordCollection to work

I imported med discogs user data several times and the wp-plugin-admin page My Record Collection runs through all 4 steps and confirms saving. When pasting the <!--MyRecordCollection--> tag on the page nothing appears. See yourself: About

Weird thing: Checking my ftp-connections wp-content > my-record-collection folder shows imported jpg-files equivalent to the 16 albums in my collection, I even generated a fresh XML-export from discogs collection on my own and uploaded it (the old one from 2011 was never updated by the plugin). No result!

Can anyone point to any working online result displaying discogs collections correct on wordpress?
