If you are having this much trouble with the game then I would recommend supporting steam and just paying the $10 for the actual steam game...

That is probably not a legit copy. Buy it from Steam. It is available for USD19.99, which is approximately 1000 Indian Rupees.
I'm assuming you don't know what Steam is Here is the download link http://store.steampowered.com/about/ Buy it from there.

Once i purchase in steam, how will i get the product? have to download ?? or they will send the CD to my billing address??

lol no , you just need to download the game.
