Thank you very much. It really helped me.

So no one is willing even to identify the problem. 

Yes, I am using IE9. What should I do to fix the problem?

Hi. I can't download any torrent. When I try, my PC doesn't 'save and open' it, but only 'save' or 'save as'. Even if I save it, the system says 'didn't succeed to download the file' in the Download Manager box. I have Windows 7 OS, Bittorrent 7.7 and Kaspersky Crystal 2.0 Antivirus. I didn't change any settings, but a year or so ago I could download torrents without a problem. Now it's totally impossible. What's wrong? Please help.
