How do I install Adobe Creative Master Suite Collection with a serial number?

I have been a student at Full Sail University since 2012. Full Sail University sent me the Adobe Creative Master Suite Collection for my program of study and I downloaded everything to my MacBook Pro when I received the Adobe Creative Suite Master Collection. My MacBook was just recently fixed from breaking down but once I turned it on all of my Adobe applications were erased. I cannot find my CD's to download my applications from the Adobe Creative Suite Master Collection and the only thing I have is my serial number from the Adobe Creative Suite Master Collection. Is there another way I can download my applications? I really need it for school please help me out!
