I keep getting this message.

Steam has found a problem with your local games file.
Games will now be re-aquired from the Steam servers.

It gives me an OK or Cancel option, I hit OK and the thing just comes up again. Cancel doesn't solve anything either. Any tips? Or should I just uninstall and re-install?

I don't know anything about anything, but this strongly looks like one of those times.

I uninstalled and reinstalled, and the same thing is happening. If anybody can offer any more advice that would be great. I suppose I'll sift through all the Steam FAQ's and common problems and such.

Uninstall it and delete your entire steam directory. The problem might be in your GCF files. Once you delete the remains of your steam directory, reinstall it and see what happens.

I unistalled using Add or Remove Programs, and when I go to search for the Steam Directory, I can't find it. How do I get to the Steam Directory?

C:\Valve\

or

C:\Program Files\Valve\

I installed mine on the first.

I don't have either of them.

I tried that last night when I was messing with it. Right now, I restored my computer to a couple days ago when CZ was working properly. I hope this works. Steam is completely redownloading CZ, so I got a good feeling about this one. If not, I'll let ya'll know. Thanks for the help so far.
