Preview arrow not working in Timeline view

Sometimes my preview arrow (in the lower left controls ribbon) grays out so that I can't preview from the timeline.  I know I can still preview from the primary preview button, but I need to set object timings.  

If I close Storyline and reopen it, the arrow reappears.  Simply saving the file or toggling between slides doesn't work. 

Can anyone help?

Thanks

Hi, Michelle -- Thanks for reaching out here, and may I ask if you can also please confirm that you are working locally as described here? As the article state, "Working on a network drive or an external (USB) drive can cause erratic behavior due to latency, such as file corruption, an inability to save changes, and loss of resources." so I wanted to rule that out, if possible.
