Had problems with new version of freestyler hanging on boot up and my pro utility was hanging as well when I tried to "find pro and connect"
USB dongle was not coming on and Freestyler hanging on boot up... Really frustrating....
Here is how I solved it....
Went into Control Panel \ Device Manager \ Ports (com and lpt) \ usb serial port (com 4) \ right click \ update driver software
I was connected to the internet, I chose the "search automatically" option and it found the driver online and installed it.
That fixed it .. the little green light on the dmx pro is blinky blinky... and i have my chauvet colorstrips running as I post.
NOW... If I could only learn how to use fixture creator to so I can write a file for my generic chinese RGBW and RGBA pucks...
