NetRadiant - Some Textures Working / Some Not

So, I've installed NetRadiant using ingar's tarbal (http://ingar.satgnu.net/gtkradiant/index.html#download) and have downloaded the mapping support pack and put xonotic-20160515-maps-mapping.pk3 in ~/.xonotic/data/

This has at least some textures working fine (alphamod, common, any map specific textures). However, none of the *x texture sets appear to work - ex2x, metaltechx, stein1x, etc don't even show as having any textures in them.

Any ideas what's up?

Back at it again with the wrong links, it's ok ,

Download NetRadiant: http://dl.xonotic.org/xonotic-0.8.1-mappingsupport.zip

Lower Quality NetRadiant: http://dl.xonotic.org/xonotic-0.8.1-low.zip

P.S I got the links from Xonotic Downloads the Official.
