Micromax Mobiles
Softwares not run

I HAVE PURCHASED 1 MICROMAX Q3 MOBILES FULL QWERTY PAD LAST YEAR 2009 WHICH HAS INBUILT MASSENGER (MSN), OPERA MINI & NIMBUZZ . BUT I CAN'T CHAT BY OPENING THROUGH NIMBUZZ OR MSN. IT IS NOT OPENING IN MY MOBILES. IT ALWAYS TELL CHECK YOUR CONNECTION OF SERVICE PROVIDER.I AM USING BSNL SIM.ON THE OTHER HAND OPERA MINI IS RUNNING WELL. TELL ME IF THERE IS ANY SETTING WHICH I HAVE TO DOWNLOAD FOR CHATTING.
