meh once my head didnt load for 2 days... i wouldnt worry it will work eventually... this question gets asked alot... they should tell everyone all these things when they buy the damned texture
Sometimes, at least for me, auto update doesn't recognize the textures (or something) and it aborts the upload. You could try uploading again, but I think stilf would be best for this question.
Still, could you paste what appears in your autoupdate log?
It might be called something else for windows users..
