I can at least confirm the issue.
Unfortunately I haven’t worked with the system yet (so take my input with a grain of salt), but my understanding is that it is possible to mark some files as available to everyone and some files as only available to those who paid more than X money. Maybe you marked the files for that by accident?
I’ve also seen issues reported in these forums where there was an index file missing, but that would have blocked the upload in the first place - I think. Again: I want to help, but in this case I’m unqualified besides an additional pair of eyes and some recent memories. :/
P.S.: Hold on… Those eyes I was just talking about spied something… Both files are marked as “if you pay $0.49 USD or more”. There you go. :)
