I have 6.5.5 (although 6.5.4 is still the version you get from the main page, 6.5.5 is available through the link Andrei posted in message #11 in this thread). Everything, including the album art, downloads just fine from Discogs. (I have Windows 7.) I did not even have to re-authenticate. But I use dbpoweramp to rip because it provides a greater range (and I think reliability) of metadata than Discogs so I seldom use it.
