I need to download Adobe CS5.5 master collection

I purchased it through school a couple years ago but recently had to get my hard drive replaced and need to reenstall my software. Can't find the disk for it, can't even remember if I had a disk or whether it was a straight download from the adobe site.

I try to to download it from the ProDesignTools site but get "Access Denied" and told i "don't have permission to access" it. None of the links work.

Can anyone help?
