Help with Emergency Computer Setup and restore

[Miraz]

Dear friends,

I was trying to watch Bangladesh Zim match through sopcast and it was not working. I tried to uninstall Sopcast software. It was taking for a while. Suddenly I realized the program in deleting/removing many software files. I tried to stop uninstallation but it was not stopping. I finally managed to stop that. Now, I have lost almost all installed software and after restarting the menubar is not appearing. In factt nothing except the background is appearing.

Now, How can I get the menubar and other system setup back?? I have opened Firefox through Windows task manager and now I really don't know what to do.

Please help.
