So I'm trying to set up my autoguider (Lodestar) to TheSkyX but for some reason every time I try to connect it gives the error "Could not open communications port. The port is either in use by another application or not recognized by the system. Error = 201."
Now I had this problem last weekend so today I tried troubleshooting the problem and put in the autoguider first before anything else, and it worked fine. However, come night time when the imaging process is actually taking place, it gives this error again no matter what I try. Any ideas as to why this is happening?
