Have you tried re-installing hackshield? I know theirs an update exe at

..\SD EnterNET\NavyFIELD\HShield\HSUpdate.exe

Maybe running that will replace some missing files?

Theirs also a

..\SD EnterNET\NavyFIELD\HShield\Update\autoup.exe

file that seems to actually install any hackshield patchs - so perhaps that might help as well.

have your tried running nf first then running xfire?

I had NF running.. windows 7 64. I had it installed under program files... I kept crashing roughly every other game in battle room. So I uninstalled everything, reintalled under Program files (x86)... now when I click on NF Launcher it updates, then when I click play game HS runs, then screen turns black, I get the blue circle NF loading thing, then it exits to desk top

OK first thing I see it the low amount of Ram you have, I would suggest you close every program you can
before starting the game.
