I just got a Sparkfun Inventor's Kit for Christmas, and I'm new to Arduino. I tried to follow the instructions. I plugged in my Uno and downloaded the software, only to be unable to find the device in the device manager menu. The power button is on and the troubleshoot button blinks. Also, when I opened the box, I found the section of ports on the Uno from RFU to VIN to be slightly bent inward. I am very disappointed in this and in the fact that my computer won't recognize it, and will be greatly upset if it transpired that my Grandmother wasted her money on a system that doesn't work. Perhaps there is a simple solution; I hope this is the case. Help!
