Iam trying to download a book and nothing is happening .Is it because I have a new computer?

Yes, if you register the second computer to the same Amazon account that you set up on the first computer. (Note: Amazon limits to six the number of devices that you can download a given book to.)

To download books onto your second computer, first load the Kindle app to the computer and register it. Then run the app and access the Archive associated with your account. (The archive will be shown as an entry on the same screen that your books will be listed or displayed on.) Just click on the Archive and you will see a list of all books that you have purchased from Amazon (assuming that they have not already been downloaded to the maximum number of permitted devices, in which case you won't see them or if you do see them, you won't be able to download them until you erase them from another machine) . Click on a book and it will immediately be downloaded to your (second) computer.

Two methods.
First: A computer is required. Connect the old Kindle to the computer it should show up as a new drive. Open that drive and find the books. Transfer them to the computer. Plug in new Kindle and do the same only transfer the transferred books from the computer onto the new Kindle.
Two: If you purchased the books from sources like Amazon, your books are saved on their cloud. Simply connect your new device and download all your books again.

idk,You will receive an answer like this if,you did not include the make or model or serial number or
date of manufacture or complete problem and what needs to be done.

Books you buy should be listed in your Amazon Kindle library.
Check it using a laptop or desktop.

If they aren't listed there then something went wrong with your order.

If they are listed in your Kindle library, you need to turn on your Kindle and connect it to wi-fi or 3G. Your Kindle should then automatically download the new books. If it doesn't, touch Settings and select *Sync and check for new items*. Make sure the Kindle you want to download the books to is listed as your default Kindle if you have more than one so new books will automatically download to it once it's connected.

Try again later. Sometimes platfom errors ocurr. I had a similar problem sometime agao with my credit car trying to buy from Amazon

Ok I have been thinking about your problem. How long did you actually charge your Asus Transformer?
You might need to charge it about 8 hours minimum to get it to work efficiently. Try that and see what happens.

1) you need to be connected to the Internet
2) there must be enough memory left on the HD
3) for iBooks: the sync. must be on
