STM32L0538-Disco Loses Programming

When I connect my board to my computer via usb (cn2) I lose the programming. I lost the factory programming to start with. I downloaded the Keil uVision5 compiler and downloaded the blinky app to the discovery board. It works until I either unplug the usb cable and plug it back in or shut my computer off and reboot. Has anybody else had this problem? If I program my board and unplug the usb cable and plug it into CN3 (USB User) it runs properly.
