BB stuck on iMatch

Got my match today, it installed easily. The RC 2060 came on and off easily. The 5ft BB went on smooth but now won't release, seems to be stuck at the center pin. I've tried dropping it on level ground and on blocks.

I guess I can try and wedge something in to lift up on the link arms while holding the BB down.

I'm sure I'm doing something wrong and would appreciate any help.

Thanks Tim
