Something has happened?
 

I am not sure what is going on? My daughter closed my computer down while I had some stuff downloading. When I started LW back up it started to install itself all over again like a new program. We had a different skin & it went to the original. My Library was cleaned out. My peer tab is gone.
I also get a sign coming up. It says I have no internet connection & that my firewall is blocking my downloads. It keeps disconnecting, but still downloads my stuff. I can do new searches. What could this be? Is this happening to other people?

If you're using Windows XP then use a System restore.
