What do you mean by "trouble"?
You'll probably get a lot faster results calling Customer Service at 1-800-THE-BOOK (1-800-843-2665), option 2 for Digital Support.
If you want to try to diagnose this over the forums, you'll need to be detailed as to exactly what you've done and exactly what happened when you did it. When you buy an e-book via your NOOK, the e-book will normally download right away without you doing anything. It takes a minute or so, especially if you're on 3G.
