I've had a problem like this before on two seperate instances and oddly enough managed to work it out on my own.

1. Try clearing your internet cache and cookies then restart your browser then try to download it once more.

or if that doesn't work...

2. Use a different browser all together.

Sometimes I get that when I download stuff using IE, but when I go to FF it works just fine. Not sure why, but give it a shot.
