I have been having the same problem with 2 files I ordered on 8/4 (order #5359950). I did not get a response to either of two emails I sent. When I called customer service, they said they'd look into it but couldn't offer an ETA or a fix. The two files are coming in ~150b and unzip to an unreadable 0K PDF. I have tried downloading on Chrome, IE and mobile. Help please.
