CATIA robot

Can somebody please help me with this robot in CATIA?
I already asked question on this link:

but person there doesn't answer anymore.
If you need any more information or pictures, just say.

If you want help, please describe the issue and what you've attempted here... sending us to another forum is poor form.

I'm sorry, I did that only because I already posted many pictures there and there was already some discussion.
Basically, I'm stuck in the kinematics of this mechanism:

When I'm trying to connect dark blue part to white one, I get the message that mechanism is over constrained and I'm not sure why that happens.
