Illustrator won't let me select or edit layers
Hi, this is my first time here and I couldn't seem to find this particular problem discussed anywhere. I'm working on Windows 10 and have had Illustrator, Photoshop and Indesign on my computer for quite a while. All programs have been working fine until just yesterday I suddenly can not select or edit any layers on Illustrator. The courser hovers over the layers and disappears when I click to select, lock, hide etc. and nothing happens. One of the layers in particular has some artwork that I can't seem to bring back after "hiding" it. I hope it's not completely lost. Thank you in advance.
*My apologies, I forgot to mention on working with Illustrator CC.
