I am using a Sony Vaio vista 64-bit. I installed the new version of MyDMX and 64-bit driver. Program works in demo mode and also detects dongle and goes into usb mode. All lights on dongle are working. Power on solid, USB and DMX both flashing. Problem is my intelegent lights are not working. I have replaced all cables (usb and dmx cables) this did not seem to help. Can anyone help? I am a noob and as much as I hate to say it I am getting rather frustrated. Have had the program for about 2 months and still not getting it to work.
