While downloading the newest firmware update on spark controller the download stopped with only 7% downloaded and crashed. I turned off the spark and restarted the computer several times and with no luck. The Spark controller now seems dead. I emailed technical support a week ago but I have still to hear back a reply. I was wondering if anybody has some advice to get it up and running or should I return it? It was taken out of its package, plugged in and now dead. Pretty bummed that I still have not gotten the controller up and going yet.
