FYI
Still happening, decided to try them again.
To get the arrow I had to refresh. No problem there. But downloading the two files I had linked from mega4up still gives a message host error use another mirror,
As well, they still do the less than 1kb file, but I assume that is because they still sit in the cache,
I then cleared my cookies and tried again, got the split worlds file from mega4up this time eith the error, but it was the less than 1kb version, I then tried the other link, Tales of Love and Hate but the mega4up link gave the error message. Cleared the cache again but still got error message,
HTH
Edited to add:
Received the mega4up error message on a few other new files today, it seems to be about thirty percent of the time,
