Change in SL wide textures?

This script worked before the last major change to SL. Now it does not. Are the textures no longer available for general use?
EDIT: This script does work fine. It just needed resetting. Please ignore this post!

default
{
state_entry()
{
llSetStatus(STATUS_PHANTOM,TRUE);
llListen(0,"",llGetOwner(),"";
}
listen(integer channel, string name, key id, string msg)
{
if(msg == "show" // 100% alpha
{
llSetTexture("5748decc-f629-461c-9a36-a35a221fe21f", ALL_SIDES); // blank texture
}
else if(msg == "hide"
{
llSetTexture("f54a0c32-3cd1-d49a-5b4f-7b792bebc204", ALL_SIDES);
}
}
}
