Well I'm having the exact same problem I had a few days ago, I tried all the exact same fixes again but nothing is working. I tried Installing it into the  "Program (x86) folder, but that didn't work. I tried exactly what I did last time to make it work numerous times. Nothing seems to be working at all. I'm running Windows 7 64-bit 
2GB Ram
AMD Athlon II X2 220 Processor 2.8GHz

When I launch NF There's not update files that download or andthing. The 2 bars just stay grey and the "Play Game" button lights up. Idk if that has anything to do with the problem but usually when Navyfield is acting correctly theres always the 2 yellow loading bars at the bottom of the Launcher when its ready to start the game.
after HSheild loads up the screen turns black as if Navyfield was about to load, then it just crashes and I get that "Navyfield.exe has encountered a problem" and it says its searching for a solution (which I know is BS) can anyone help me? I've tried EVRYTHING i can possibly think of Clean reinstalls and everything. I'm just tired, been at this all night trying to get it back up and working and nothing seems to be working... Im going to bed.
