"memory allocation for 5413928 bytes failed"

That′s the message popping up if i start my Singleplayer game.
To make it short, i have no idea what this means and what i have to do to play my game.
-I had the "Xfire Broadcast" running when this happens-
But it worked the whole 5 hours before with the broadcast.
Well the game crashed sometimes for some reasons while Broadcasting and even without the Broadcast running.
Thanks for support.

It means the game does not get enough memory from the allocator. Not knowing how that thing works internally it might be that you don't have enough available memory in your computer or graphics device (probably the former).

but the amount he has quoted is only 5 MB which is tiny? what are your system specs OP?

MA specs are:
Win7x32
Nvidia Gtx275
4Gb Ram
....
well i guess that its not ma computers problem.
