Try "dragging" it back to where it's supposed to be. Move your mouse to a blank area of the "taskbar" which is now on the right side of the screen. While holding DOWN the left mouse button, "drag" the taskbar down to the bottom. It should relocated itself along the bottom.
You mentioned that you can't see it at log in. Have you accidently made it "auto hide"? If so, after it's moved to the bottom, and depending on the operating system, RIGHT click on a blank area of the taskbar, then UNCHECK "Autohide". (If you're using Windows XP, RIGHT click on the taskbar, choose "Properties", then UNCHECK "Autohide".)
Hope this helps.
