Update MM and install this plugin:
DiscogsAutoTagWeb_V5.71

Hi,
You are using an older version of MMW as recent one points you to new plugin that works.

Amazon stopped this a while ago: http://www.mediamonkey.com/broken-auto-tag.htm?l=en

Just purchased latest Media monkey and now Auto-Tag from Web gives me:
[b]Couldn't show results.
HTTP/1.1 400 Bad Request[/b]
Same result for different search options- canada, germany, uk, usa
Also, no results for look-up artwork.

This worked before with older version of MM. Am i missing something?
Thanks.
