Can't get Mac App Store

So here it is;

I once had SL and upgraded to Lion through the Mac App Store in early August.
I then experienced many problems with Lion and decided to go back to SL with my Installation CD and made all the updates available through the software updates.
But now I don't have the App store and it says that all the available updates have been made. I'm running OS 10.6.8 at the moment.

Any other way to get the App store?

thanks

Have you checked its not in your Applications Folder and just need dragging to your Dock?

yeah, it's not. By the way, my macbook is a 2010 MBP 15' 2.4.

Not sure how much the App Store integrates in to the OS, but if you PM me your email address I'll upload a copy of the App.
