Basically, I somehow lost access to my External Drive and had to Format it. I waited like 4 hours for this entire thing to be recovered using the app "Recover my Files"
However, now when I wanna save my files, it's asking me for a username and an activation key which I dont have.

I've been panicking because this is my dad's External drive and there's a lot of important stuff in it, and now im being locked behind a paywall.
