And not sure if this helps your cause, but I just downloaded, successfully burned, and am currently playing BOTH BoF 3 and 4.
Make sure you download all parts of the file, I just put mine on the desktop and then create a folder afterwards. Make sure just to leave the file naming intact as it is when you download it. Put all the files in a folder, and extract only part1.rar, it will automatically detect the other parts.
Might I suggest you use 7Zip? It's a tiny program, and integrates so nicely into the Windows Right-click menu. And not only that, but it recognizes 1001 different extensions (not literally, but you get the idea). Oh, and its open source/freeware
, how could it get any better?
If you could perhaps post which program you used, your browser, and other settings like that, we could help a little bit more in-depth.
