It's a safe bet that other downloads (we are not talking installing?) fail I'd look to what changed since downloads started to fail.

When I download itunes my Toshiba laptop (Vista) it only boots to 'please wait' and will not go further. I then have to restart in safe mode and restore to before the itune download. I have reduced my popup blocker to minimum as recommended. Nothing seems to work. Expert advice very welcome.
