Videos are not playing in Articulate Review

I am having a similar problem. I have one slide with links to 6 short videos, each on a separate layer. Now when user clicks the link, they are directed to the correct video but only the title screen shows (even though the bar indicates the video is playing) and the audio is always that of the same single video. (i.e., they click the "contractor" link and see the initial shot of the "contractor" video, but they hear the audio from the "farmer" video. Always the "farmer" audio regardless of which video is showing.) Earlier versions of the course worked fine--the videos played correctly. i cleared my cache. We use Chrome. I am using SL v3.44.23192.0 Thanks
