I guess these requirements will help you...
To send and receive SMS messages via a mobile phone using a Windows PC, you need:
a mobile phone that can be connected to your PC (some mobile phones do not have an interface for connecting to a PC)
a Windows program that can control the mobile phone to send and receive SMS messages
Today, most mobile phones support at least one of the following options to connect to a PC:
Via infrared (IrDA)
Via a USB cable
Via a serial cable
The infrared and Bluetooth option should be very useful to many notebook computer users since nowadays many notebook computers have built-in infrared or Bluetooth support.
The Windows program for sending and receiving SMS messages is provided by some mobile phone manufacturers. For example, Nokia offers a software package called Nokia PC Suite to their mobile phone users. It can be downloaded free of charge from Nokia's web site. Microsoft has also released a free program called SMS Sender that enables Windows users to send SMS messages via a GSM mobile phone from a PC.
In the following sections, we will explain how to use Microsoft SMS Sender to send SMS messages on your Windows PC.
Hope this will help you..have a nice day! Or try to reinstall the CD (pc suite) on your laptop or pc, this will make it very helpful as well.
