I know this is old, but I ran into this problem last week, so I want to share what I did to resolve it in case any other users have a similar problem and are looking for help.
Basically, when I installed Courseware, none of the subnav menus or text editors were showing up on my custom theme running BP Template Pack, but they worked fine on BP’s Default Theme.
I tried to follow the instructions here, but I noticed that the BP Template Pack plugins.php file already had the hooks that it needed (bp_before_group_body and bp_after_group_body), so that wasn’t the issue.
To fix the problem, I copied and pasted the plugins.php file from the BP Default Theme over my custom theme’s plugins.php file (the one created by BP Template Pack). I then made the necessary (div) adjustments to make it work with my custom theme (exactly as I had done when initially setting up BP Template Pack). Voila, my sub navs and text editors appeared beautifully, all within my custom theme.
