The problem is that the counts that appear above the social icons are not coming from our publisher account, the numbers are the same on EVERY page we have this displaying on. I have double checked my publisher id in the code above 10 times and it's correct so I have no idea why this is happening.....please help!
I'm not overly familiar with ShareThis.com, however if you could post a link to the instructions you are following, as well as the page where these buttons are not working, I don't mind taking a look for you.
I toyed with this for a while. I ended up using http://share.lockerz.com/ and it works perfect. Much faster than ShareThis too. All you have to do is add a img inside the li (I believe) for custom icons.
