Shortcut "W" (Specials) misses Loop Tools

Hi there, I’m using Blender 2.6.2 and when I want to use Loop tools using the shortcut “W” (Specials) the first option should be “Loop Tools”, instead the list begins with: Subdive - Subdivide Smooth - Merge…etc, missing the Loop Tools.

How can I access Loop Tools or the shortcut in 2.6.2?
Thanks for any information about this matter.

Have you enabled the Loop Tools addon?
Have you tried disabling it and then re-enabling it again

Most likely the addon isn’t enabled. It’s not on by default. I don’t know why because It’s a great addon among some others that I think should be on by default.
