I total understand that.

Can you point be at the file and line where this exception occurred?  

I just don't see that this string matters as it is never passed to any PSM API.

I suspect if all instances of `Parameters["Texture0"]` are restored to `Parameters["Texture"]` things would work identically on PSM.
