I am using Windows Live Mail Software to manage all my mail accounts. Since two months ago, I have been unable to open/save any attachments from any of my accounts. But if I use browsers to download the attachments, everything works fine. So I believe  there is something wrong with the software. Do anybody know how to solve this problem?

BTW: the software doesn't give any error messages or warnings when I try to save attachments.

Thanks!
