Thank you so much necrox.
I have used the Web Console (that's how I find the 'get' request information showing the 302 file moved info), but I have never used the Network Monitor tool. The quick video tutorial you made is perfect, and I look forward to peering further into that tool.
BTW. I *thought* I followed your (first) instructions to a "T" because it worked great! Ha. I went back just now to change the referer per your recommendation above, and saw I never populated it.
So I downloaded the file successfully without a referer! That doesn't seem like it should have worked. Maybe because I had already been downloading from the site via web browser and it was cached? (Not sure what Ketarin shares with the system or default browser.)
Since I delete the garbage out of the browsers frequently, chances are next time there is an update Ketarin will try to download when browsers are clean and I haven't visited the page. If it fails I'll populate the referer as above and try again.
Thank you again for your time and effort not only to solve this one but to help me learn to help myself. Give a man fish, he eats for a day; teach a man to fish and he'll eat for as long as the same kind of bait works :-) I'm always in the market to learn new Ketarin bait.
