Frank,

The other problem I have is that I've been personalising my cart by following instructions in the thread and then found a thread saying that core files shouldn't be changed (english.php ones). Well the thing is they are the ones that were mentioned in the threads and they're the ones I've changed.

I'm worried about the difference it will make you see. Will I lose all my changes? Do I have to do the template again?

Yup, you are right, first time upgrader with very cold feet!
