Error trying to import .bvh files by Linda Kellie

Hello, I’m trying to import .bvh files that were originally created for Second Life by Linda Kellie several years ago (and are now available at Zadaroo.com). But they won’t import and I get an error report instead. They import OK into Second Life, just not into Blender. I don’t get this problem when downloading other .bvh files created for Second Life, just LK’s collection.

Here is a screenshot of the error report.


I’m using Blender v. 2.77 on a Windows 7 computer. Any thoughts? Thanks!
