Here was the link back when the problem happened in July.  Short of trying this, I'm not sure what else to suggest until I hear back from the programmers on what other trouble shooting I might try.  I've downloaded the file and extracted the contents with no problem, so it's difficult when I cannot duplicate the problem on my end :(

Please keep me informed, and I sincerely apologize for the inconvenience.
