This is the solution that has worked for me every time my textures wouldn't load. Normally I use Phoenix, but when "ruthed" I go inworld using the SL 2 viewer, and hit rebake. If that doesn't correct the problem, I change into a different avatar from the SL 2 menu... like a robot or non-human of some kind. I continue to hit rebake until my avatar loads. The longest it took was 5 minutes.
