What about copying your whole system layout into a new osd file and then set the layout parameters like the ones in your original osd file? I remember once having to implement the system again in a new osd file (I had made the connection, but after I opened a subsystem and made some changes in it, the connection was not there and when I wanted to connect again, the “already connected” error was displayed below the layout. I guess I made a mistake by saving the file then. I am not sure though). But that’s all I can say. I hope it works, or you get technical help from Optiwave.
