Hi all i know this may sound like a stupid question but i can't seem to find the mix strip or where to turn it on.Any help would be great thanks

Click the MixStrip tab in the Inspector (red arrow points to tab), then right-click in the MixStrip for the menu shown below the red arrow.

Thanks Scook i'm all sorted

I have installed the MC7 with all available content and I don't see any modules in the mixstrip but the EQ. Where is the Grit, Space and Max?

 

you need to click on the plus sign next to where the box says untitled this will bring a menu out which has grit space and max.Just select which ones you want.

or just right click on the header of the EQ and it will bring up a menu asking if you want to insert a new module. 
 
if you have a module in the Mixstrip other than EQ, and you right click on its header, then you will get options to remove or replace also.  EQ is not removable, tho, but it doesn't have to be powered on.

As you can see on the screenshot I only get an "Empty" field by pressing the "plus" button.

No, RMC on an EQ module doesn' help. I only get an option to remove modules.
