So...
I may have accidentally unplugged during an active debug (not 100% positive though as I was in a rush).
But I am positive that the PC is now not "seeing" the MSP430.
When I plug in the MSP430 it shows up in the device manager as "Generic USB hub" with a warning sign.
Checking the properties of "Generic USB hub" gives:
"Windows has stopped this device because it has reported problems. (Code 43)
The USB hub failed to reset."
The previous program (which blinks the green and red LEDs) that was flashed is still running on the device.
The Green debug LED is on, while the red is not.
Using CCS gives the same "Error: No USB FET was found" error.
As does the MSP430Flasher.
What should I do to fix this? Or should I just buy a new one?
