Import Error

[jhwblender]

Hello,
First, thank you for this importer! Although I tried importing a file and got an error (attached).

The file I am using is from RC Desk pilot. I have attached 2 example files
(I changed the extension to .txt so that you can download them from here. You'll have to rename the extension to .x)

Thank you,
Jesse Wood

In case you haven't noticed, the author hasn't had any activity on GitHub since 2013, and the website's contact form is broken (tries to use Capcha v1, so blocks all messages). Also, though people trying to fix it (see forks), the author hasn't added a license which can really discourage developers from fixing it for him.
