So after downloading 3 mods on fallout 4 ,using the nexus mod manager, my game ran fine for about an hour then it crashed. After the crash my game will not open. i have deleted and uninstalled all of the mods and Fallout will it open. when ever the fallout menu comes up( the the one with the where it says, play, options, settings and technical support) i click play, the menu closes, and then the same menu opens again. i am not a really good tech person, so tell me anything that might help, even the simple things.
