Not sure about Android, but the site does not function well on my phone (iOS). It does function, but there are a number of things that don't work at all or don't work well.

Sam, I've had the same problem recently, as well.
I first noticed it when I bought Tormentum, then realised it was like this with ALL my games here.

GOG support denied having made any change, even though I could download things normally form every other site - it was only here on GOG that I had the problem. And now it seems Judas has confirmed there HAS been a change.

I had to switch from IE to Chrome, to download things.

Have you tried using the old Gog downloader? That should still work.

We changed our naming structure for our offline installers.

If you can, please try Chrome or Firefox or Microsoft Edge for now. I've managed to reproduce the issue with Internet Explorer 11 on our end and I've passed on the issue to the right people but it may take a few days to fix :)

AAH HA !!!!

I knew this was some sort of test.......
put the glue on the fence,
shove the cat through the hole,
and presto, chango............

Thanks for letting us know.
Now I'm not so perplexed why all the sudden I couldn't download.

My bandwidth resets in a couple of days, so by then maybe I can resume downloading.

Thanks

Just as a FYI, there should be nothing stopping you from downloading, you just need to rename (also removing that [1] or whatever it is at the end, in case it checks for the other parts of a multi-part installer by looking for files with the same name instead of having a clear list to look for).
