when I try to open the NMM it shows me an error window saying "Error loading the following mods:" then it lists the path to every mod ( http://prnt.sc/czljvv ). I have an option to choose just OK and then I get a new error message titled "missing mods" and it just goes insert mod name cannot be found, however, a different version has been detected. The installed missing version is XXX and the new version is XXX (exactly the same version). It asks me if i want to upgrade the mod and when i press yes it goes to the next mod, and when i press yes again it opens the next message(too long to write): can't post link cause I have low reputation I press yes and choose Fallout 4 and choose the path to my mods and press finish and it goes back to the beginning of this thread.
I posted this on reddit and someone answered with:
First thing to check is the your E: actually exists. If it's an external drive it's possible Windows changed the letter. If the drive does exist make sure the path is correct and exists. If that is true then you should run a disk check. Right click on the drive in Windows Explorer and choose properties, goto Tools, and run the Check under Error Checking.
If your E: doesn't exist (because the letter was changed or something) then you'll need to tell NMM where to find the files now.
And that is my answer:
I've checked a few times and yes it is E: and the path is good, windows didn't change a thing. I've ran the scan and it said everything is fine. I don't remember how but a few days ago when I posted this on a different forum I got a tracelog (?): can't post more than 2 links cause I have low reputation
I still need help.

Alright, here's what I've discovered. The current version of NMM (I'm on 63.6, not the newest) there is an option to enable Multi-HD Install mode.
This can be found by choosing your game, and once the main NMM program loads, click the Wrench and Screwdriver symbol, and click on "Change Virtual Folders." Check the box next to "Enable Multi-HD install mode", and give that a shot. Theoretically, it should solve your issue.
