need some help because we can't find the solution even after doing a search here on the forum. Maybe we missed the obvious but let's present the problem. computer with win7 and M-Pc soft. 3.20.450 uac & firewall off doesn't recognize the connected usb duo dmx box. tried all possible things we could think off; even a complete software reinstall. after several trials M-Pc now sees a usb duo dmx box (menu-system-dmx settings-usb2dmx) but nothing shows up in routing and the box next to the command line reads 'Free'.
I am having the same problem. Running Windows 7 on an Acer Touchscreen PC with USB DUO. I upgraded from 3.0.440 to 3.20.450 and also updated the fixture library. The USB DUO seems to be found ok when I look in the menu. Nothing seems to be running. For instance, selecting a cuelist and hitting 'Go' does nothing. If I select a fixture and change the intensity it shows in the programmer but not in the output. As with the above post, I see 'Free' in the box next to the command line.
Any advice gratefully received as I need to be running again by the weekend.
