Another user (forexblue) even purchased a new camera to try and see if it would happen to him and sure enough he had issues. Since you can now add cameras, and I cannot get my two V3’s to work, I am wondering if somehow the Cam Plus system sees the Mac Address on my two cameras and has flagged them as something else. I have changed the names but cannot change the mca address to see if that would alleviate the issue.
