Magnum - thanks a lot for the info!
so i guess im not the only one taken to dekstop without the game quitting and being able to do memory flush. It sure does happen often though
fatty - thanks very much man! i really appreciate it, that was the problem - administrator UAC thing. Now it finally works to export to mp!, thanks goodness cause i was afraid my "attack nazis" mission was all for nothing

as far as nvidia drivers go this issue has been happening to me on many versions throughout the years/months, but in arma or sims3 it happened once in a rare while. I tried IF with previous and newest driver versions, still same thing. It could take me to dekstop as often as every 20 seconds to every few minutes. As i understand from Magnum others r having this problem but i only heard ppl r having disconnects problem and the game doesnt crash exactly, just takes me to dekstop so is everyone doing the memory flush thing every few minutes like me too? i gave up after a while lol
so is it really only the game that needs to be patched, its not that i dont have enough memory or too old video card or something?
