Hi oldmac! Welcome to the forum!
As pyxiwulf and exscentric have said (and you probably have discovered by now) the reset button (actually a hole) is what you need when/if your PE gets stuck as it did. I had to use the paperclip trick on mine soon after I got it, but never since.
Hope you got it going again! If you want to you can try Kenny's suggestion. It is optional, so don't worry if you aren't ready yet.
The update you started on (from the enTourage Updater) is something you should do, so I hope you have now gotten it done.
Let us know how you do!
