Miley Jab Hum Tum Update please

I was not watching 'Miley Jab Hum Tum' for quite a long time as I was not getting Star One in my cable. Now i recently got a new connection and started to watch Miley Jab Hum Tum again. But now I can see many new characters and rest of them are acting as if something really bad happened between them.
Can any one please update me what happened between Samrat and Gunjan? What happened to Nupur? Is she dead? If so what happened?

yes nupur was dead but our power of fans brought her back with druv who loved her since morena that is why they quit morena and it is druv who did the accidnt and samrat was driving that day so gunjan thinks it is because of sam who was driving fast
