My Mydmx dongle recent went dead. Symptoms are...red power light is lit... DMX light is flashing contantly at a high rate whether a DMX cable is attached or not... The USB light comes on for a second when the cable is attached. When I start the program it immediatley defaults to demo mode. I am using new DMX cables and this whole thing was working perfectly. If it is in fact defective, who do I contact to return it? Thanks in advance for your help.
