First, reinstall OS X 10.8.2 > http://support.apple.com/kb/DL1581
If it doesn't work, press Command and R keys while your Mac is starting and reinstall OS X, so you won't lose any files.
Finally, you shouldn't use cleaning apps to remove applications. They can damage OS X, so you will have to reinstall OS X if it damages the operating system

The Messages application is part of the operating system.
Open Disk Utility via the spotlight in the top right.
Select "Mac HD" and verify it. Then repair it and that should fix it. If not then you will have to archive and reinstall the operating system.

That won't work. Disk Utility's Repair feature only works to repair the filesystem if the hard drive appears as damaged

You won't lose anything reinstalling the operating system, but first, try to reinstall 10.8.2 only using the link I gave you on my first comment

I thought verifying the OS and it seeing part of it missing would give the option to repair, if that's in fact not the case, I apologize. Good to know @mende1.
If this isn't the case ^ then yes, the supplemental update as first step or reinstall via recovery.

To be strictly correct it is an Apple App that comes with the OS and is Updated at various times but when the OS is updated.
As an example Messages was at version 7.0 in OS X 10.8 and 10.8.1 but in OS X 10.8.2 it was updated to version 7.0.1
However it does have to be in the Applications folder (And not in any sub-folder within that) to get updated.
I have heard of people creating a "Messaging" folder and putting Skype, MSN, Yahoo and the Messages app in the folder and the Updater cannot see it.
Messages as a whole consists of the app itself and several support frameworks on the "System" side of the Hard Drive.
If you have Time Machine and removed just the app then if it is Up-to Date you can restore it from the Time Machine Back up.
In some cases you can get and Older version then "Run the COMBO" as has been said to update it before launching the app.
Tools that specifically remove apps are likely to also remove the support structure and will not work via this method.
