That's a pity. That ransomware should offer an unencryption if you pay those criminals that put it on your PC (or tricked you into putting it on your PC), but after reinstalling Windows you lost the details (such as a link) needed to contact them.
All you can do, I'm afraid: retireve those files from your backup.
