Lost icons on top 'toolbar' and in Finder. MacBook Pro

Lost icons on top 'toolbar' and in Finder. Can't get them back by shutting down MacBook Pro (Summer 2012) or with command: killall SystemUIServer

All the icons are there in other logins. The 'icons' work when clicked on, but never appear. I lost them after my laptop froze and I had to shut down by holding the power button.
