At the top, click where it says the Blue Question Mark in the right corner of the browser,  then on  "About Internet Explorer". A box will appear telling you which version you are using.

If its version 7 - click on 'Page' then make sure 'compatibility view' is not checked

If its version 8 - Click on Page, then on Compibility View.

If its version 9- you need to either use a different browser or un-install version 9 and re-install version 8

We don't support version 9 so if thats what you have installed, it will cause problems viewing certain areas of the site.
