Over the summer, I attended a STM32L seminar. I got the board to connect and program perfectly on my work laptop. Since then the board has sat in my drawer, but I just recently got out to use on a school project. On my computer at school, I can not get it to connect. In my device manager it shows up under universal serial bus devices as a STM32 STLink. I have been following the guides I got at the seminar, but it isn't working. My OS is windows 8.1. I have been trying to get this to work for a few days with no luck. Any help is appreciated.
