@Manumiter,
The described issues were due to the virus scanner AVG. If you are also running a anti-virus solution, try to disable it and test f you then can access the configuration.
Thank you for the assistance. Perhaps you could look over thread "TV Configuration Always Crashes on Channel Search - New Win10 and MP2 Install" that I posted yesterday. I did not quite get out of Richa99's posts that the conclusion was all due to a virus checker. Besides, I am working with a fresh Win10 install on a started out scrubbed hard drive with no third party virus checker installed on it. So are we saying MP cannot deal with Microsoft Win10 default firewall and virus checker that installs with a fresh install of the O.S.?
