Ok... I was chatting with one of the guys on the VA I belong to (United) and he basically went through all that you said when uninstalling the CS767 and then reinstalling! We deleted all files belonging to CS767 (as it is the only CS product I own).

Anyway, I was then looking at the program ACE which has tabs on the top Fleet - Preflight and Tools.

I then noticed to the left it says in red "DEMO MODE" Activate Product.

So, after speaking to one of the pilots that does own this aircraft, he said that when he tried the aircraft before buying it (demo) it also had a blank panel and open windows.
So just logic tells me I am installing a DEMO version of the aircraft.

My question is firstly WHY do I have a DEMO version when I bought the aircraft?

Thanks in advance and hopefully this sheds some light on the problem!
