Short answer:  You can't.

Long answer:  See http://www.bleepingcomputer.com/virus-removal/ctb-locker-ransomware-information for lots of information.

There are suggested methods of recovery there but quite likely they won't work.  You can pay the ransom if you wish to try that method.

Short answer - either restore from backup or pay the ransom.  I don't suggest the latter, especially since you have wiped the information that would allow decryption with a ransomed decrypt key.  So most likely this will not work.  If you don't have a backup and you can't get it back to the state before you cleaned it.  You don't have much chance.

System restore only works for your operating system files,
not your data files. You need a separate backup(s) for them.

This is a long shot. There just might be some unencrypted old versions of some files available.

You will not be able to unencrypt the files, but you may be able to get back many of the files from a backup that is automatically created called Shadow copy (that is if it was activated to run before your files got encrypted). By default shawdow copy is turned on.  But some of the CBlocker viruses also encrypt or destroy your shadow copy files. You may be able to try using ShadowExplorer to extract files from your Shadow copy.  http://www.shadowexplorer.com/downloads.html
