ST-Link V2 Troubles... (SOLVED)

One of the unlucky few who can't seem to get ST-Link to work.

I'm trying to connect an STM32L-Discovery board via CrossStudio. It uses ST-Link V2 for direct USB debugging. I can ping the part just fine using the ST-LINK utility, but when I try using CrossStudio, it gives me a ERR_UNKNOWN_MCU error and the next time I try to connect it tells me it can't connect. The ST-LINK utility also can't connect. I can reconnect when I unplug/replug the board.

Any idea what's going on?

EDIT:

Nevermind. I noticed ST-Link connects via SWD, not JTAG. Changed that in CrossStudio and it now works.
