I'm pretty sure you haven't installed it
The 3.0.xxxx version on Settings:Plugins denotes the DAY it was released.
And I think that I've released 2 versions on that day. A procedure which seems not to be foreseen by ST's plugin handling.
To get a valid statement, compare the "Build number" on the W&C plugin settings page with the build number displayed on my plugin settings page (www.sporttracks-plugins.com
If different, install the plugin from the plugin settings page.
