I went the same route as Kaom did when upgrading from Bryce 4 to 5 where you had to give them the serial number that came with the software and they replaced that one with another. It's a good thing I wrote it down somewhere safe where it wont get lost but I can't remember where that place was. dBgrafix, if you're using MSN Explorer it brings its own download manager which you can use instead of the download dialog window. It gives you a download progress report as you download and tells you how much time is left to the download.
