I am doing some preliminary work on a MiVoice 250. I currently have the system sitting on my desk while I program it. It will not let me access System Administration and Diagnostics. I get an error that says, "AWS Webpage and Advanced System Monitoring are not available." I can access Database Programming with no issues. I upgraded the software to 6.3.7.78. I also have another 250 right next to it with the same software version. I can access SAD on that system with no problems whatsoever. I am puzzled as to why it will work on one and not the other. Any suggestions
