I have the 1.1 version of this software. It works, but sometimes it has some glitches. I'm trying to make this version work, but I can't seem to be able to connect with the COM. If I try to send something to the sign it displays: Failed to open COM! Also in setup I already followed the instructions of the tutorial/help section, but when I try to look for the COM it cant find it. Any suggestions on what I'm doing wrong?
