Alternative to Acrobat for PDF

For about two months, I haven't been able to open my Acrobat reader for PDF. I've tried uninstalling, downloading, reinstalling, about three or four times.

Baz 'Adobe Sweet Adobe' le Tuff sent me this link http://www.foxitsoftware.com/pdf/rd_intro.php for a third party reader. It's only 1.2mb and workd beautifully.
