Sorry, I don't save it but I find the cause of the problem.

@razazel : I make a try with profiling branch, I got the error.

I make a try with last RC version in 64 bits, it's work. But my clan play with stable version...

Yes, I have tried to reinstall, it doesn't solve.
I also try to delete yourprofilename.vars.Arma3Profile, it doesn't solve.

I got exactly the same problem, it's been 2 days now.
