How to use author pane tpl with the forums?

Hi there!
I´ve created an author-pane.tpl.php file to use with advanced profile kit. And it works ok.
I hoped that this file could be replicated to my advanced forum author pane, but it didn´t.
So I created another file named advanced_forum.blue_lagoon.author-pane.tpl (blue lagoon is the forum theme that I´m using), and put that file inside my theme folder.
It didn´t worked.

I´ve tried to follow these instructions, wich tells me that:

The first thing you need to do is determine what template file you are using. This is the trickiest part because Author Pane is designed to be made use of by other modules. You can use the theme developer submodule that comes with the Devel module to help. Here are some likely candidates:
* author-pane.tpl.php: This is the default and is used if you call Author Pane as a theme function.
* advanced_forum.STYLE_NAME.author-pane.tpl.php: This is used and provided by Advanced Forum.
* advanced_profile_author-pane.tpl.php: This is used and provided by Advanced Profile on the user pages.

I´m pretty much sure I´m missing something here, but cannot determine what...
Any help on how to solve this will be very much appreciated!
Thanks!
