Problem with SainSmart Nano V3

I am having trouble with a brand-new SainSmart Nano V3 (ATmega328). The code that I am trying to put on the board is not uploading, but will still compile. The same code works flawlessly with my UNO. When I go to check the port, the usb port I am using is not a choice, which leads me to believe that the computer isn't even reading it as a device. I tried downloading the appropriate FTDI Driver, but to no avail. Even after installation, the stupid board isn't working. I am at a standstill in this project until I can make this work (shows me for buying a clone). Any help is much appreciated; thanks in advance.
