I'm having issues with the Stats Editor as well, after the latest patch. Worked fine the day before the patch.

Several nodes missing, same as helaene reported. But I'm also experiencing not being able to open several of the nodes that are there.

For example, when clicking on "Armor" under Equipment, I'm getting the following error:

[StatsEditor] Can not load document.

The detailed error is the following:
[StatsEditor] Can not load document.
Detailed error message: Cannot load stats because name attribute is invalid.
