If you still have the panel at the bottom of the screen, right-click on it, slide over Choose Options, click on Add Widgets and you should see Application Launcher. Double-click on the icon to add it back to the panel.
If that doesn't work, you might want to start over. Simply exit X (so you've got a console), make sure you're in your home dircetory and remove the
.kde directory then
startx; e.g.,
Code:
cd to your home directory
prompt: rm -r .kde
startx
Not a "fix" per se, but really effective (and, of course, you have to redo settings, preferences and all that but you've got a clean start to work with).
Hope this helps some.
