We highly recommend using Mozilla Firefox for your browser.
It's very easy to download from their website and it's an open program so it can be used on Mac PC OR Linux operating systems.
By the way, I tried to update our Internet Explorer version and it was quite complicated, but it took no time at all to download and install and start using Firefox. Firefox also makes it easy for you to transfer your fave sites etc from Internet Explorer too so don't worry 'bout it!
To download Firefox just click here:

you'll be up and running in no time!
