To activate reader, first cradle your Axim and go here -
http://das.microsoft.com/activate
Sign in with your Passport username and password. If you don't have one, you will have to create one.
When you get to the activation part, click for pocket pc.
That should do it on activation.
Now, I don't know a lot about the reader software...so I had some trouble that I didn't anticipate. I d/loaded from Amazon to my laptop, and it opened the book right up, and when I transferred it to my Axim, it was locked! I don't know if there is a setting in the desktop reader to keep this from happening, so I deleted it from my laptop. Then Amazon wouldn't let me d/load it because the program wasn't on my computer!
So, here is what I did. I just d/loaded it directly to my Axim.
Cradle your baby, then direct IE to amazon.com. Up near the top right, there is Your Account. Click that, and sign in to Amazon with your email and password. There will be some links that some up. Click on track packages. It will tell you if your order is ready to d/load. It took 2 days for mine. I don't know why...maybe they have to scan each book by hand! (You realize, I was just kidding when I said that.)
If it is ready to d/load, click digital library. Your order will show up, and to the right there will be a link for d/loading.
I hope all this rambling helped. I am sure you can do it another way...if anyone knows about how to keep desktop reader from opening it and messing it up, let me know. Not that I will install it ever again...I would just like to know if there is a better/easier way!
