Unable to connect to TM4C129X

After working through the example of how the ADC conversion works on the TM4C129X, I decided to next upload the example code for the microSD card. I put the card in while powered, which I see may have been a mistake. I then tried to upload the example, and I got the "Error connecting to the target: Frequency is out of Range," and I decided to unplug the board, and plug it back in. I then noticed that the 3.3V Led is not turning on. My computer is also not recognizing the device in the device manager as I might expect. I attempted to use the LM flash manager to unlock the debug port, but so far all I am getting is "ERROR: Failed to unlock connected device!" 

At this point I am more or less certain the board is done. Is there anything I may have missed?
