Is it just me, or will that link not open the pdf?
Sometimes a PDF file will open in your browser and sometimes in a third party application like Adobe Reader or FoxIt, depending your software configuration, but you can force it to save to the hard drive by right clicking and selecting "Save As" or something similar to that.
You may already know this, but since that file was uploaded to RapidShare you'll have to open the page and then click "Free User". Then it'll count down from like 32 seconds and finally give you a download button to click.
