Sorry for the late answer, real life has its ways of keeping us busy sometimes. I did a bit of research but there is no good answer. Sadly the 0xxx hasn't been decrypted yet and assuming the user had internet access during the infection, it's safe to say that the 0xxx got a unique encryption key that will make it impossible to decrypt with the current tools. Furthermore, the ransomware removes both volume shadow copies and system restore but it never hurts to double-check.
Talking with a friend that is working in Emsisoft there might be a new tool that will be released soon and can decrypt a lot of the new Djvu variants. For the time they will keep a low profile about it as they don't want the ransomware makers to get knowledge ahead of time and it's only been tested under strict NDAs.
So what you can do is
a. Keep a backup of those files in their encrypted form and hope for the best.
b. Format the PC and make sure you remove the source that the ransomware broke into your PC.
c. As always keep both offline and online backup of files. With the current prices of online storage, there is no excuse not to have important files backed up.
Wish I had better news for you.
