Guys, I need a clue.

Took part in the spring in Bitradio

Put the purse.

  I have a past wallet.dat in the program folder and in the backups folder files wallet.dat.2017-05-10-08.53 (with different copies of the save).

Did the OS reinstallation. Now I've installed the Bitradio client again ... I'm waiting for the synchronization ... but I tried to restore it in the summer, it did not work out.

Tell me - how and where to attach backup files?

Thank you!
