Hello @ashughes and welcome
I have only seen the videos and even that not very carefully so please excuse my freestyle improvising here.
Depending on where you are based, you can try contacting a reseller or a local Angel
I would not force it definitely but I would double check the battery - perhaps it is protruding in the way? you could unscrew it and screw it back in place, also checking the battery connector
You could also provide us with some shots, perhaps some other FP6 owners could have a look?
