Plugged in my ZenMiner today, but it would never register on my network.  Finally hooked it up to my PC with the HDMI cable to check it out.  It's asking me to install an OS, and anything I click on says "This will overwrite the current OS".  I do not have an option to exit or boot to an OS.

Did I get an SD card without the ZenMiner OS on it?  Also, the miner never registers on the zenminer site.
