recovering software after hard drive crash

My hard drive recently crashed, before it died I was able to backup my programs. Now I can't get my dvd x platinum to run because it prompts me to register and the company went out of business. Any way around this problem? I'm running windows xp-home edition on an HP thats 3 years old. I have 756mb of ramm installed with a new 160gb hard drive. I also had the adobe creative suite installed and can't reload it due to being only able to licensce the suite on 1 computer. I have it on my laptop currently but want to put the creative suite back on my pc. Any help would be appreciated.
