Error when HS3 starts up

No problems with the plugin running, but the following error presents itself when HS is starting up: "Could not add SqueezeBox to the plug-in list. Is this a duplicate?"

Looking at the startup log I'm seeing the following:

Jul-22 1:52:05 PM Error Could not add SqueezeBox to the plug-in list. Is this a duplicate? Check for two plug-ins with the same plug-in name.
Jul-22 1:52:05 PM Plug-In Found plug-in: SqueezeBox, version: 3.1.2.10
Jul-22 1:52:05 PM Plug-In Found plug-in: SqueezeBox, version: 3.1.3.2

How would I go about getting rid of that old version?

Thanks!
