Can anyone tell me how to fix my camera on N8.. When I click on the camera button, it came with this message, "Unexpected error occured. Please restart the camera. If it does not help, try restarting the phone."

I already restarted the phone, still it did not work, I even did a "hard reset" hoping that it would go back to its normal settings but it didn't..

I've read that i should install CameraPro but still it did not work..

I did have a problem updating it to symbian belle because my Ovi Suite came also a system error message.. That is the only thing i did that made my camera stop working..

Also i did install the "multiple mods" seen here but still it did not work..

I see that the cover of the lens of the camera is not opening.. Why is this happening.. Can anyone help? Thank you..
