Well it installs fine but once it get's about a little over half way it says download complete you can now disconnect from internet. Once that comes up the bar freezes for a bit and then says Download failed now deleting backup files and all this stuff. I used to have .network but my computer got a virus and wouldn't even let me log in so I just did the system recovery (which made me restart everything) and now it won't install. I need .Net Framework 3.0 because I just got Sony Vegas Pro 8 (I'm a amateur film maker) and I can't install it until I get this. Please help!
