Has anyone else encountered a recent problem while compiling projects using mbed online compiler (error message goes "Struct "" has no field "NRFFW" "RF_UICR->NRFFW[0]" in fstorage_config.h? I haven't changed anything in my project. IT was working on 7/20/16, then something happened, and since 7/21/2016, it no longer compiles. The same is true for imported projects like BLE_HeartRate. The target board is NRF51-DK.
