I can't locate the data files for FO4 anywhere on my C: drive. Ran a file search, and got nothing....I would like to install some mods, but can't without access to the data files.... Any ideas on where these files might be located?

I just updated to NMM 0.40.1, and now when I run Skyrim from it or the SKSE Loader it blanks the check boxes on all of the mods. The only two that it shows as active are skyrim.esm and update.esm nothing else will stay checked, or run. Any ideas or thoughts on why this may be happening? I uninstalled all of the mods, deleted them, and then re-installed them...and it's still doing it.
