Manual addon update not working

[EQBallzz]

Today I tried to update some addons with the "update" button and the progress bar that normally goes quickly and updates within a matter of seconds is going slowly and never completing. Eventually the bar just stops at full but never completes and still says "Updating". I have tested my Internet connection and not having a problem there. I have tried a couple different addon updates and they both are doing the same thing. I tried restarting Windows but that did nothing.

I'm using Win7 64 Pro if that matters.
