Hey everyone, i've got things working now. It's a very unorganised process in my opinion, but i got it done. I opened Explorer and went into Onedrive. In my Documents library there was a a notebook. I clicked it and it opened up in Edge. It accessed my data from the internet. I selected import, and most of my notes are again accessible.
I'm guessing i was asking a question so basic that it didn't even cross people's minds that this would be a problem... So with that in mind, if i wanted to create a new notebook, how would i do so? Would i have to do it in Edge?
