I don't know foff44, sorry.
Sometimes I have there problems, too. I download ever each item as a single download. One of my last was a tutorial from G@P and some other things. I downloaded the tutorial three times not right and had only 2 times for download it again. I wait some days and then I downloaded without any problem (it can be sometimes a problem with big files, I think).
In cornucopia's forum I don't read realy often. Have you post there your problem? I think you get an answer for this.
Hexagon: Tested last month the very first tutorial with the "Chair". I began 3 times and it's not really easy to learn for me. The tutorial is very good as always, but I habe to learn there a lot.
But it is nice to know that I can do one day great things like "Fishing Village".
Thank you so much for all those great tutorials vovka and Gary!
