So for the past several weeks i've been running the beta version of Arma2 operation arrowhead's base .exe file; as is required to have steam community overlay running without crashing the game on startup.
the following alert pops up in my logs at every second while the .exe file is active.

i've already sent this error over to the developers over at bohemia interactive (the studio that designed the game) so see what they can do in the next beta patch they release.
