DayZ Works fine, but Operation Arrowhead Won't Load

[cbale2000 0]

So I've had Operation Arrowhead and DayZ for a few weeks now, so far I've been able to play both interchangeably with no issues until the past few days. Now I can launch DayZ through the Six Launcher without any issues, but when I go to launch Operation Arrowhead or Combined Operations through steam, I get an "Error creating Direct3D 9 Graphical engine" message, and the game does not load.

Is there any solution to this issue? I have to think it's a problem with DayZ as DayZ would not work if it was a problem with Operation Arrowhead.

If it helps, I'm running:

Windows 7 64bit

Intel i7 950

6GB RAM

nVidia Geforce 480

I too am having this issue, did you ever get your vanilla OA working? If so what did you do to fix it?

Both OA and Combined OPs work for me now, though the only way I've found to get OA to run without DayZ loading instead is by going through the Six Launcher. Combined OPs works through Steam without issue though.

Honsetly I didn't actually do anything to fix the problem, I want to say there was some update that resolved it. One day it just decided to work again.
