PP CS5.5 and CS6 reinstall ?

[ImInDraftMode1.0]

after a RAID repair, PP "disappeared" and the backup doesn't find/reinstall it, so I started over with the disk procedure, and now have CS 5.5 up and sort-of running.  Years ago had the same issue; how to get CS6 reinstalled and not recalling if it was a download or what...My original version is the Student Teacher (The CS5.5) production premium with all the bells and whistles (Photoshop, AE, AU, etc). 

Thanks in advance for assistance with this...

If your programs were registered with Adobe, you will find all the particulars in your account.

Serial numbers and if they are downloads etc.

Usually you cannot upgrage a student version so it must be a full version.
