Try rebooting.

If that doesn't work... you may wish to look at the amount of content in your runtime. I remember a previous report that having a massive amount of items in one's runtime could affect the application of MAT poses to hair. I don't think anyone figured out what that amount was.

Of course you can always apply the textures manually.
