Usually, if you de-register your kindle and re-register, amazon should send your device a certificate file. However, for after changing the serial, amazon's server refuses to send your device a certificate (maybe a recent change because it worked before). Anyways, it basically blocks you from whispernet by refusing to send the device a certificate.
If this happened to do, contact me. I've finally figure a way out after hours, but it's complicated. It involves extracting a backup cert, breaking the encryption (find the password), then modify it and use it to generate a new certificate.
I'm not sure why this happened. It may have been an accident, like I was trying to register in middle of a maintainance, but to be safe, refrain from changing your serial.
