Hi. I have been trying to learn the ShowXpress software, (latest version) and finally got to the point of connecting my iPhone.
I could not get it to connect, called tech support and was told the new version of ShowXpress had too many bugs and I should go with the last version. Which I did. Yesterday when I had the 512 interface connected, the pc link light stayed on constantly but had a rapid flicker. I could use it to control my lights from the computer.
Now today after getting everything set up with the old software, (and I did get my iPhone linked) the pc link light on the dongle goes on and off repeatedly, on for about 5 seconds then off for about 15 seconds....making the lights work when the pc link light is on, and then stop working when the pc link light goes off.
