Why doesn't my Last.fm (audioscrobbler) plugin work with Foobar?

I'm currently using Foobar2000 v0.9.5.

The audioscrobbler plugin version is v1.3.15.0.

The plugin is located in the C:\Program Files\foobar2000\components directory.

What's wrong? unsure.gif

EDIT: Issue resolved with a reinstall of the Last.fm client.
