Downloads don't work

[stopmejune]

The first blog I added listed the type as "Tumblr hidden" despite it being a public blog--but I assumed it was something wrong with that particular one. Trying a few others, they list the number of downloadable items but the downloads never initiate.

I don't get a red background colour telling me it's not working, either. There's just no activity at all. Starting to wonder if I'm using it wrong altogether because I'm pretty sure it should be working???
