importing c3d files into motion builder

Hi guys,
I'm new to the site and new to motion builder 2012 in general but i'm having a few issues with importing c3d files. I recorded some martial arts footage at uni and the tutor recently emailed me the files, but when I open them up in motion builder the dots load up under the grid and on it's side... The file plays the animation perfectly fine but I've not been able to load up the file any other way as the results are the same, and when I go to put the 'actor' character into the scene to start binding the dots to it, it loads up in the exact center of the grid on the top like it should do..
Does anyone know what it is i'm doing wrong please or if it's a fault of how the footage was recorded or emailed to me?
Any help would be greatly appriciated.

Rotate the Reference

As I understood your issue, You can rotate the reference node of your optical data to the appropriate position and orientation, And then do the rest with actor and retargeting part.

Select through "Navigator" or "Viewer" window. For Schematic View hit Ctrl+w. Then Move and Rotate to desired location. Find the attached files for a visual reference.

Thanks for replying again. I have followed through with what you said and I have managed to rotate the dots to the orgin mark. Only thing is that once the animation starts to play through the dots go right back under the grid again even when I try to keyframe the dots in place. Do you have any advice for this also please? I have also spoken with my sports prof and he is looking into the axis configeration of the recording equiptment as he said a lot of biomechanical software has the X,Y and Z axis lined up differently to that of animation/motion builder software.
Thanks again.

I use Vicon Blade, and the c3d data we export always comes in upside down and to the right. All i have to do is grab the main sphere that's location at the center of the grid (hit ctrl + A to make sure its showing), and rotate it 180 degrees, and 90 degrees to make it right side up. However, it always stays in that position when i rotate; i never have to key anything. Its wierd that you would have to set a key. I would play with the motion file import settings. One time i had a separate issue, and it was solved by checking a different box when importing.
