Can't create new layers
I'm in the middle of trying to finish my final when all of a sudden, I can't make new layers and it won't let me copy existing layers. I've tried closing up the program then opening it back up. I've tried making new Illustrator files to see if it was just the one I was working on that was having troubles, but it seems like across-the-board on all Illustrator it won't let me make new layers or copy existing ones. Please help!
