Problem with reinstalling from a disk Create Suite 5 on new computer

I purchased a Creative Suite 5 Premium (CS5) via disks in 2010; I know this is an old program, but it is perfectly sufficient for my needs as a professor (this was purchased as an educator, and I mainly use Photoshop and a few other programs, including Acrobat).  I have deinstalled from old computers and reinstalled it on new computers via the disks several time.  However, my desktop switched to blue screen and then died before I could de-install CS5.  How do I find a way to get around this problem without paying an exorbitant amount of money for only a 1-year online download?  (I cannot afford to do this at all.)  Thank you for any help, or any suggestions on how to contact Adobe directly for them to "deinstall" (i.e., remove the link to my dead computer so I can reinstall it on my new one), as apparently they will not respond to anybody who purchased a project more than a year or so ago.  This is financially devastating!
