I bought CoursePress Pro because it said that it had a live chat feature that was above and beyond what the lite version would have. Now that I've installed it and got a demo up and running it's telling me that I need to buy a membership for $99 a month in order to use the chat feature.

I would be alright to purchase the plugin outright, but I don't want to pay an extra $80 a month just to use this feature that was promised to me before purchasing this product.
