importing manuscripts into ID CC

I've been away from ID for a while, but i need to continue now, and have many manuscripts that need to be converted and formatted in ID.
Problem is, what i used to do isn't working anymore.

I have files converted/compiled from Scrivener into various formats. I've tried them all. RTF, Doc, Docx, etc. Instructions say to create the ID file, with all the settings, etc, and then PLACE, do SHIFT+click into the first page. Not only does it not autoflow and create pages, it doesn't paste the text AT ALL.

Nothing happens.

Has something changed with ID?

(please, don't tell me to use Word or create books in ID, I use Scrivener. I also have 60 books, and they are already created, so I need a solution that addresses what I'm actually dealing with. Thanks in advance for any help).
