Recovery the key of my pdf architecs downloads

I lost everything in my computer. I had to re-install the original system in my computer. Now I am trying to recover my pdf architects units. I paid for them couple months ago. 

I made a big mistake and I deleted the keys of my pdf architects!. 
Please, tell me if its possible to recover my key if there is an option. 
I paid my pdf architect with my credit card of Wells fargo.
Please, I need your help
