With the closing of the HP Catalog, I gather there is no way to reinstall the Kindle App? Mine froze and when I went to deregister it, it shows as deregistered in the Amazon "Manage Your Devices" but is still listed as registered on the Touchpad. Trying to deresgister from the Touchpad leaves it spinning (it being the Kindle App, the TP still works). What I'd normally do in this case is uninstall and re-install the Kindle App but can no longer do this. Amazon Support said they do not have access to the app and they do not support it.
