Hi all. Just thought i'd let you know, in case it affects you, that my  "unable to load texture/out of memory" error has now been solved...thanks to the Smith Micro team who reacted to my ticket extremely quickly.  I only had this problem with my "clothing" textures (Dredded underscore problem?) and the secret is to install any clothing runtime folders in the "C" drive / My Documents folder (Vista home 64bit) and NOT on a separate drive. Kinda defeats the object of being able to use external runtimes, I Know, but IT DOES WORK!!!  Yippeeee!!!

Hope this helps some of you.

Thanks SM for the assistance
