Couldn't help you on this one without looking through the rest of your code
more carefully. For instance, when you pack your data, did you made any
mistakes? Did you allocated only 2 bytes instead of 4 bytes
etc? UnpackRange is the function that gives you the error message, but the
error could be somewhere else.
