"The good news is hell is just the product of a morbid human imagination.
The bad news is, whatever humans can imagine, they can usually create." - Harmony Cobel
We are helping you. It's an error I've certainly never seen before and judging by other posters, they haven't seen before either. A search of the boards doesn't pull up anything like it. We know the software is fine because lots of other people update with no problems. Therefore it makes sense that the issue must be your side in either the uploading or the server config. I've posted in our team forums asking the devs to have a look for you.
