Can not get DNS protection to run / no longer a valid problem

Since I installed AIS 15 I can not get my DNS protection to run. The program keeps telling me something is not started, then when I click the turn all on I get a message telling me the following could not be started but it doesn’t show me what couldn’t start. The active Protection page shows me that Secure DNS is off but I can’t turn it on. I had been using OpenDNS but have uninstalled it hoping that that would solve the problem but it doesn’t. Any advice?

A reboot and reinstall fixed this. Thanx
