Looking for RedBear Nano BLE header file - BLE_API.h

Hello:
I’m trying to run the Blynk Arduino sample program for the Nano, and I get this compiler error. I cannot find the file and I’ve installed the latest Blynk and the RedBear libraries. I’m using Arduino 1.6.12, and Windows 7.

C:\Program Files (x86)\Arduino 1.6.12\libraries\Blynk\src/BlynkSimpleRedBearLab_BLE_Nano.h:26:21: fatal error: BLE_API.h: No such file or directory
#include <BLE_API.h>

Program code is:
