SERVER NOT FOUND

I’ve been using CID for a number of years and love it. I upgraded to Win 10 a couple of months ago and things were fine. About a week ago there must have been a Win upgrade of some sort because its been playing hell on my CID. The only thing I can get is Server Not Found screen. I’m using Firefox now but would like to get my CID back. I’ve uninstalled and installed CID a number if times with no change. I tried the advance network setting on CID to the same as Firefox setting but still no change. I stopped Windows 10 firewall and my Comodo firewall but that didn’t help
Any clues as to how I can get my CID to find the server??
