In order to work with another piece of software, I have installed kindle for PC ver 1.17. It works fine, but for some reason will not receive new books. I have de-registered and re-registered several times using both the default location and amazon.com. I have tried my old email address and my new address, making sure it is the correct password (incorrect email or incorrect password will not allow registration but I thought I'd mention it) None of these changes will allow this copy of Kindle for PC to register properly. it never shows up in the registered list of devices.
Can someone help me understand what is happening.
