Do you know what conditions the breeder had her living in? And when she was a puppy was she in the crate for long periods of time? One problem that you can run into is that if a puppy cant hold it and is forced to soil its crate, it can stop looking at it as a clean place and loose its sense of hygiene.
I was actually just going to ask a similar question - if you know what conditions she was raised in before you acquired her...
Sometimes dogs that are raised in conditions where they are caged pretty much all day have no choice but to go potty right where they sleep, eat, etc. They can be MUCH harder to potty train than dogs raised under other conditions, because they don't have that innate sense of not wanting to soil their "living area" - they have no boundaries, so to speak.
I am NOT saying that this is the case here, but it is just something to keep in the back of your mind if you think there might have been a chance she was raised like that.
You are obviously a great Mommy with a lot of patience - it just may take a little MORE patience to get her through this...

Hang in there!
Now that your computer is back up, any chance of a picture?
