kandz8808 That's awesome news! It means that you aren't having issues with things like antivirus set-up, although you might have had an issue with something else in your folder, like a custom resource.cfg file.
Next, you can copy files out of the renamed folder into the new folders that game made. That means copying files out of the old Saves into the new one, etc. Use those new game-created folder. Start with CC, in batches so that if a batch doesn't work, you can remove part of it to narrow the culprit down. This is a great opportunity to also reorganize your CC! I keep mine organized by creator name.
You might find How to Use Mods and CC useful, as it goes into detail about what to do when the game isn't working.
