* I get the following message when I try to activate the plugin after activation:
* The plugin has no valid header.
* I use WP 3.3.2, BB 1.5.5 and Buddyboss theme 2.0.3

* I receive the same error. No response to your post in 2 weeks, so it looks like
the plugin author isn’t too concerned about this. That’s unfortunate.

* I received the same error. Fortunately, this error occurred only when I click
the “activate” link just after the installation. So, basically, by going back
to the “Installed Plugins” and activating from there, worked for me.
