I’m using version 2.63A. Error is show with an image in pdf in the link provided. Srry, had trouble uploading an image, firewall maybe? http://www.filefactory.com/file/6tqu0rf7eglz/n/Blender_pdf
Not able to see your file but for loop tools you need blender with a revision number 46803 or later. See https://sites.google.com/site/bartiuscrouch/looptools
Try the 2.64 test build http://download.blender.org/release/Blender2.64/
or from the blender buildbot site http://builder.blender.org/download/
or graphicall.org
The file is there, you have to scroll to the bottom and download pdf, but thx, I will give the test build a try. I had a duplicate copy of the tools on my desktop and it might have caused some setting problem??? I deleted it but still had an error.
yes, it’s working now in the 2.64 test build! greatly appreciated!!
