STM32F302R8: No Ulink device found

Hi, I'm using an STM32F302R8 board to do some basic DSP work. I've been using my desktop with windows 7 on it for a while and I'm able to use Keil V5.14 to program the board no problem. 

However, I have to move to using my windows 8.1 laptop, I'm unable to program the board. When I connect the board though, i do get the folder popping up showing that windows is able to see the device no problem. Also the driver is installed fine and ST-LINKV2 is showing up in device manager. 

I get an error saying ' NO Ulink device found'. When I check Cortex-M Target Driver Setup > Debug, the Debug Adapter field is empty. 

Is this a known issue with either KEIL or ST-LINK and windows 8.1? that's the only delta i can think of between my working and non-working setups.
