Loop Tool Circle behaving strangely....

Hi, I am having some trouble with the loop tool circle, it’s acting very strange.

So this is the selected vertexes

After pressing circle I got this result that I honestly have NEVER seen before.

You can find the addon I used here:http://wiki.blender.org/index.php/Extensions:2.6/Py/Scripts/Modeling/LoopTools


Does it still freak out if you Apply->Scale first?

how would I do that?

Select the mesh in Object mode, hit Ctrl-A and select Scale.

oh, thank you very much, that did the trick.
