Re downloaded the game after about 1 year of not playing last time i ran it was with mods. Every time i open it i get a security pop up error windows 10 and when i go to my security settings history to see exactly the purpose the list is blank and it closes off. I know I had a similar issue when Manchu update arrived for EU4 but I fixed that by changing allowed programs EU4.exe on my windows defender, I've tried that trick on CK2 and did not work. Any tips or links that may help would be greatly appreciated.
