Hi
I have managed to get the PDF download setup on my products page, but clicking on the link shows the download is an 'application/octet-stream' rather than a pdf file.
It can be downloaded and then opened by manually selecting a pdf reader, so the data is there, just the bit saying it is a pdf is not.

I have tried this on 3 different PCs, with the same result and it never happens for pdf files from other sites.

I guess I have to tick a box somewhere??.....any hints or tips would be greatly appreciated!
