First off,
TGC have probably stopped sending it out now as presumably the development has moved on somewhat.
I can tell you that in any case as I had earlier pointed out here at the forum - there is absolutely no advantage in having the version of FPSC that I have, over and above the EA version as it has no benefits, improvements or additional features of usable value - other than weapons are somewhat improved.
But there are installation problems which might mess up your current one.
As to the addition of the Physics engine in the version I have at least - using it slows down FPSC by around one third and reduces the fps acordingly - as a result generaly speaking - its unuasable and I have switched it off. So any value is removed.
You are really best advised to wait for some kind of stable and improved release - which would put you in the same or better position than I as at the moment I have stopped development with FPSC altogether and await the V1 releaase just like everyone else.
Of course I cant get it to you. Get my wrists slapped.
I have offered to post a video of the Physics in action if TGC say I can - but it will take a OK from them first- cant to any more than that. Sorry.
