is it something to do with having texture colouring on all the layers?
Can anyone/Lilly help?

I keep getting the same error message right now and I haven´t used textures…
You still have access to the folder in question, right?
What are the file permissions on the folder? Is it possible that you no longer have permission to write to the folder? Double-check this by doing a “Get Info” on the folder that’s popping all the errors.
Did you go in manually and add a folder in there? Or change the structure at all? Or move the project file out of the directory structure?
