Yes I simply refunded the transaction with Paypal, the transaction ID is 69H8261508405150G.
Okay, to be absolutely clear, the user was using Free Download Manager and the download got to around 50% after 6 hours and then came back with a "invalid username and password" error. At that point the customer contacted me and I checked my E-junkie logs, which stated that they had made ONE download attempt only.
After refunding the customer, I tried the download on my own internet connection with Free Download Manager, deliberately stopping it at 50% , there were no issues completing the download, but it took only 20 minutes for me.
"We particularly recommend buyers should only ever use the standard download manager built into their browser"
That's completely impractical for large downloads. Customers get 70% through a download and their internet hiccups, without a download manager they are starting from scratch again, not acceptable.
"so if it tries to download more parts than the number of Attempts you permit for the product, that can instantly expire the link"
That's what I thought might be happening but definitely not the case here.
"Note that reactivating an expired download link just resets its expiration countdown"
Yep, reactivated link after failed download, customer starts to download, gets 6 hours in and the download says "invalid username and password" and won't continue. E-junkie logs say "1 download attempt".
My theory is that the download took so long that E-junkie's download system simply timed out and that the access to your cache was then marked as invalid or something like that?
