Anyone can help.

I tried to install multibit in pen drive but see some flies also in my F drive (hard disk partition) so i unstalled multibit from contrlpanel. I use windows 7
after uninstalling it i see entire F drive of my hard disk is blank. All data loss.

The multibit version i used was multibit-0.5.17-windows-setup

Do anyone experience this? or how this happen?

Any help?
