This is my first time using vixen and am trying to get the adjustable preview to work. I followed the howto videos, but every time I try to play the sequence, i get an error message saying plugin error, the port com 1 doesnt exist, execution as stopped. All I have selected in output plugins is adjustable preview, and I don't have any devices connected to my computer. I know I'm overlooking something simple but I cant figure out what. any help would be great. Thanks.
