Cannot load file into TM4CGXL

Hello, I am new to microprocessors. I have a Tivia TM4C123G Launch Pad. I have installed uVision V5.29.0.0 and Tera Term V4.104 on Windows 10. I have loaded the Hello World Project which compiles without error but when I try to download it I get no ULINK2/ME Device Found. Tera Term seems to communicate with the board though since when I press the reset button it displays Welcome to the Stellaris LM4f120 Launch Pad. Thanks.
