Previous Button disabled without reason
I am desperate for help! I have a course that previously worked fine. Today I opened it to check it prior to publishing it and putting it in our LMS, and now NONE of the previous buttons work in it. I have tried deleting the triggers and adding them back in. I have tried taking the previous button off of the player and putting it back. Nothing seems to work. The next button works fine. And the JWS shortcut navigation keys (Alt P) works to go to the previous slide. However, the previous button is always grayed out. Please help! File attached.
