My kingston u3 launchpad installed pendrive is not working.

Hello,

I had a kingston 1GB Data traveler Pendrive.

U3 launchpad also installed.

It worked properly in windows XP.
But it doesn't show up/loads/works now in windows 7.

How to get my important data from it.
Tell me how to get data from that drive.

Thanks in advance.
