Show Cue System

I am doing a project and needs a speaker to be too far to be connected to a sound desk but could be connected to another machine on LAN running SCS as a receiving device. It is a speaker for a microphone that needs minimal delay (But not ultra low since the face is not seen) Is this something SCS on...

Ok, I'll do that! Hoping it was just going mad......

Randomly I'm getting error messages like:
Great, now I want the error codes it won't fail :/

It was something like invalid memory address scsxxxxxxxxxxxxx was the file (X being unknown)

No other program does this and no settings where changed, what's wrong???
