I'm having the same problem too

yes zozo. I updated to version 1.10 but still having problems with the cut scenes in Maxwell. At least now I'm past them I can continue, just need to dodge the artillery fire!!! :-)

still not fixed for me either :-(
Tried the spamming of LShift+Numpad- Flush and that has done the trick. Just keep flushing through the cut scenes and when you report in for the first contact (He should salute you and then speak) If he just stares blankly flush again. Flush through the briefing and then should drop you to the armoury to loadup. You should be able to assemble and start the mission after that. What a palaver At least I can now complete Part 1 ready to start Part two

I'm having the same issues:
Arma3 version 1.08.113494
Windows 8.1 Pro 64-bit
Radeon HD7870 - Driver 13.251.0.0
Intel Core 2 Q6600
Various use of space bar and save, exit & resume means I can get to the cut scene briefing for Tipping Point but when the briefing ends I can't do anything other than abort. Seriously frustrating now
