Never used the app, but you can try deleting the .bak extension, or rename .bak to .zip and try to extract it.

Won't help if it was encrypted zip. He needs the password.

No other help I can suggest other than to fork out the money. What phone did you have? Major manufacturers have their own software you should have used.
