Dear friends, my KDR and my gameplay have both vastly improved since i last wrote. My KDR is now 1.47, and my high killstreak is 25. my killstreak rewards are predator, attack helo, ac-130, and its been workin out great. however, my ps3 is no longer working. it does not read any disks. DOES ANYONE KNOW HOW TO FIX THIS. i looked up tips and tricks on the net but found nothing. and i REALLY dont wana pay sony $100 for them to fix it. also, i already tried the 'fan check' thing. can anyone PLEASE help?!
