Fatal Error - Multiple Library

Everytime I start unity I get an error saying:

Fatal error!

Detected multiple Library folders within your project.

Did you copy a project into this project? Use "Export Package" to move assets between projects.

You need to remove the following Library folder(s) from your project before you can open it again:

C:Users/axel/Desktop/Fps - project/Library


I don't have multiple folders... anyone know what the problem is?

did you try to drag a package into you project file instead of properly importing it

if you did you are going to have to manually delete all the stuff from that package in your project before it will work again

or scrap your whole project and delete the whole sucker
