I went through this similar problem a while ago becareful.

It has to do with the cookies storing old pages so the Tabcorp page thinks you are still looking at it yesterday.

This is a problem with the way your service provider connects to sites and cannot be fixed through your own settings.

I also have the same problem with other sites including Pro-punter.

The solution is this.....

Instead of hitting the refresh button (this does not eliminate the stored data) press CTRL + F5 on your keyboard which cleans out stored webpage data.

You should then see the correct page.

Hope this helps.
