I've installed this at a fresh new blog as per the Installation section, and tested from a few machines. Yet looking at the stats page, it's not tracking anything.
My new blog is at http://www.shiroikuma.co.uk (can you tell from the html if its working or not?)
On the maintenance page I keep seeing "It looks like you need to update the structure of one of the tables used by this plugin. Please click the button here above to reset your table (all the data will be lost, sorry), then deactivate/reactivate WP SlimStat to complete the installation process." next to the Reset Stats button, so I've tried that too... but nothing.
I hope you can help, thanks.
