$149 LOL ?
Not only will I never pay that for any version of this plugin, but I will also uninstall the free version right now :D
I suggest no one pays even half of that for the "pro" features. If you need some of their "pro" features, let me know what you need and i'll show you a free plugin that has it.
For example: bbpress forum attachments - https://wordpress.org/plugins/gd-bbpress-attachments/
