Hi Kev, nice to see you back again.

I've had the same problem for years but as it is very intermittent I had just learnt to live with it. What can I add?

I allow 5 downloads per product and if the first attempt is unsuccessful the other 4 will be as well. Obviously though I don't hear from those who are successful on attempt 2, 3 or 4.

Mostly I just email the file for ease but on the occasions I have later reset the downloads and asked them to try again they are successful so could it be session linked?

I've had customers make successful purchases only to come back a few weeks later and buy something else only to find the download fail.

With me the downloaded files always appear to be smaller so the download seems to end prematurely.

When it started I spoke to my host but they could not identify anything. At the time they had a customer who was running an oS Cart on the same server and they had a similar issue. The only consistency my host could find with theirs was that whenever the problem occurred MSN Bot was on their site. This did not seem to be the case with me so I think this was just a coincidence.

Chris, I still have a corrupt copy on file that a customer emailed me way back when the problem fist appeared. I can send it to you if it helps.

Finally I've never been able to replicate the problem.
