Could you see if the data is stored in
%appdata%\biblepaycore

Just see if that folder has complete admin rights?
Is biblepay-qt unblocked, and has rights to run as admin?
Try renaming wallet.dat to wallet.old and see if it runs with a config?
Maybe try installing this on another PC, just for kicks and get it mining, it might be revealing, somehow.


EDIT: One more thing, ensure in windows you create the file with notepad.
In windows you need a CRLF between each line (not a CR).
