taskbar icon missing in windows 764bit of avast 7free

So i was happy to learn that the updates work now, but during this time my taskbar icon has gone missing. I tried to reactivate it, by unchecking and unchecking it in avast and the start orb. still no luck. I know that avast works, it is highlighted on the taskbar, etc.
Any suggestions? Thanks!

Did you reboot ?

well what do you know? Here I thought I was messing my computer up trying to modify my start orb, and all I had to do is reboot. I thought I did this before the new update happened. Thanks very much.
I will go to sleep happy now! ;D
