Micromax x510 - camera module not ready - Nokia N95 Cellular Phone

I purchased Micromax Van Goh last month. Within few days of usage it is giving following error when I try to use camera or camcorder:Error ''Camera Module Not Ready''. Any solutions?

Hey friends
I purchased my X510 last July.10days back I dropped my phone since then it is showing 'camera module not ready' wen ever I happen to switch on the camera.
One day i was sitting and was browsing through my apps on the phone.I started Nimbuzz (a preloaded app) I registered on it and then i got got the solution to the camera problem. These r the few steps u can try

1) Go to application in main menu
2) Open nimbuzz
3) Register on it
4) Click your name on top of the screen
5) Select 'Set Display Picture'
6) Select "from Camera"
Now it will show a blank black screen for next 5 sec. and the your phone will restart in about 5 sec. Now try to switch on your camera & it will definitely start.Click pictures as usual.
