warfighter problems

apparently origin/ea doesn't support the games they make. this game stopped working after the finding faraz mission. tried reinstalling, updated my drivers.... nothing. sound is also all screwed up getting an echo when someone speaks, is it my video card?

Pulled up a lot of Google results for this....pretty crappy if EA can't even bother fixing their damn games. Anyway here's a fix I read.
