Right. Sorted.
Package upgraded to RC1.6
I only made a couple of minor changes to advertising.php and the GUSH_main template and the GUSH_ad_row template.
To upgrade, download latest package... Upload all files to their respective locations overriding any old files in the process... then run the templates portion of the installer. This will update these two templates. You then may need to revert the GUSH_main and GUSH_ad_row templates.
Then you should be able to view the stats (please remember the viewer isnt done yet - think of this as a preview

)
