Rekordbox deleted

Hello,

I had some OS trouble with Windows 8.1 and finally the only way to restore my laptop was a Windows Recovery, it means that I lost Rekordbox and all my playlist, cue, etc...

Anybody knows some posibility to restore this? I only have a copy of the ProgramFiles(x86) folder, and a folder in a Pen Drive with a file called export.pdb.

I haven´t got copy of C:\Users\User\Appdata\Roaming\Pioneer, that I seem which contains the main data base files... :(

Please help me! I have lost a whole bunch of work hours...
