Mac App Store not launching following system restore

[BoyBach]

Hi guys and girls, I recently restored my iMac using Time Machine and now the Mac App Store app no longer launches. The icon appears in the dock and bounces for about five-ten seconds before disappearing. Everything else works seamlessly following the restore. Any help would be gratefully received!

Did you re-applying the 10.6.6 combo update?

I had to do a full system restore from TM following a disastrous download attempt of iPhoto 11 from the App Store. It works fine, so I don't know what happened to you.
You can follow the instructions on this page:

and it may work for you. Best of luck!

Just a quick update to say that reinstalling the Combo update fixed the problem. Thank you maflynn!
