Thor I remember you saying something about not being able to d/l Beatscape a while back. And now the same thing with the DSF stuff? damn!!
I know this ain't helping you but I did like everyone else, d/l the DSF files, installed with no problems.
But I have had problems like this before. If it were me, I would disable all you virus stuff, get a d/l manager, or use Firefox or Chrome.
I don't like Internet Explorer. Just to show you what I mean:
I regularly surf the net using both FF and Chrome with no problems what so ever. I just had IE 9 up and running, was impressed by it's looks and maybe giving it a chance. As I tried to scroll a few pages it was stuttering to do that! Come on! I closed it and won't open it again!!
