Storyline crashing when inserting characters?

I see this is an old thread, but I recently installed the Team version of Articulate and have run into the same problem. I added a character to another storyline slide with no problem. Then I created a new file and after trying to add a character (which shows him on the timeline, Articulate froze up and I had to end task. Has there been a resolution found for this? Otherwise, characters are out for me. I don't have the time to troubleshoot.
