OK, have now attemnpted to download this game a total of 3 times now, each time with no success. I have had to cancel the download each time, as the game has reached around 70% downloaded and then resets the download. Unfortunatly I don't have unlimited ISP access so that is it for me for the month for attempting to download this game.
I don't think it is my Stardock settings, as I have recently downloaded the beta for Gal Civ 2 DA with no problems (it is now installed and running).
I haven't as yet receieved any further responses from Stardock in regards to fixing this problem or coming up with further suggestions for this issue so at this stage, unless I hear something from stardock by the end of the week, I will be asking for my money back. A shame really considering the demo was so much fun.
