Any times I want to play at Arma 3, edit mission or other I've got the message :
"The instruction at 0x......... referenced memory at 0x0000000000. The memory could not be written."
My team have the same problem.
Impossible to play since the 1.50 update
I've tried all Malloc, verified my game files.. Same problem..
But rolling back my game in 1.48 and all is working fine...
