Unable to download any file from WPMU Dev

I chatted with your live support and Jack Kitterhing said to escalate the problem here. Every file I try to download ends up as an uncompressed archive that contains a single file named: wp-login.php, which Jack said was your login php file.
I recently renewed my membership after having let it lapse for a while. My id is Walt4D. Here is what my membership page says: Walt4D
