When I initially installed, I couldn't get the product to work on my Mac. However, after posting a trouble ticket, I received immediate assistance and got up and running in no time. I love using VideoScribe! It does require some learning--and resources abound for learning how to use it--but it's an excellent tool and I'm so pleased I found it. For those who are complaining, it seems to me that they haven't taken the time to contact support. My experience with support (and sales) was phenomenal. They really seem to care about customer support. I don't leave many reviews but I'm happy to in this case. It's a 5-star app, and company.
