Well I did everything you guys have mentioned but the Taskbar still won't appear when I put the mouse to the top of the screen.
NOTE: This only happens when I have "Let Start11 enhance the taskbar" enabled. I did not realize that before. But yeah, when that is enabled the Taskbar will not come back after it disappears, unless I hit the Windows key.
It's actually no big deal because I prefer to have that functionality disabled anyway. So without it, save for a few glitches here and there, everything seems to be OK.
Thanks for all your help!
