I had our children's ministry leader contact me saying she was having an issue replacing a video on Proclaim (the latest version as of 10/2/17) - When she would go in to change the video item in the list and import video, it would immediately crash when she clicked "Add" on the screen where you can add tags. I tried it on my Mac and got the same result. She uses a Windows machine. The workaround is just to add a new "Video" item and import the video there. It worked as expected. I'm pretty sure this is the first time we've encountered this on any of our machines.
Thanks!
