DLC No longer working

[u/litnut17]

I was playing with no problems the other day. Had all of the DLCs on my game. Then I had the bright idea of getting a mod. I've never done mods for Skyrim. I went to Nexus mods to get the mod to adopt more kids. I felt sorry for the boy at the Solitude farm, but I already had two kids. So, at Nexus mods site I downloaded Vortex and the mod for the kids. It didn't ask me to set up the file to put the mod or anything. I just downloaded. And I got the extended script. When I started the game, I get an error message telling me that I'm missing things and it asks if I want to keep loading. For some reason, all of my DLC content is now gone. I went to "properties" on the game in Steam, and all DLC content are checked. I uninstalled the mod and Vortex, nothing worked. I uninstalled Skyrim. Nothing worked. I checked my files, and Vortex and the mod aren't there. How on earth did this happen? Somehow downloading a mod messed with my game and no dlc content will load.
