I am assuming you now have a different Internet service, therefore your Time Machine is connected to a different modem, the Expresses or Extremes are in different places, and you quickly encounter John Galt's Rule of Networking: Changing anything changes everything. You might as well reconfigure the Expresses from step number zero.
"Hard Reset" one unit, make it work, and then configure to the next. Read the FAQ to ensure you perform the reset correctly: Resetting an AirPort Base Station or Time Capsule FAQ

Aiport Utility was unable to find your Airport wireless device after restarting.
The settings for this Airport wireless device have been successfully updated but there was a problem re-joining the wireless netqork or finding the airport wilress device.
I went through the process now a few times and this continues to happen.
Suggestions on this issue now?
Thanks!

When you "hard reset" an AirPort, it creates an open network with the name "Apple network xxxxxx" that your computer must join to configure the AirPort. When you are finished configuing your new wireless network and subsequently restart the AirPort, the original open network "Apple network xxxxxx" that you joined to configure the AirPort ceases to exist. AirPort Utility then complains that it can no longer join that network or it just sits there waiting forever.
After you create your new wireless AirPort network, your computer must join it. This may or may not happen automatically, depending on your computer's settings. Look for the network you just created and join it.
If your computer cannot find the network you just created, then something else went wrong. This can be due to an error in wireless security, a firewall problem with your computer, wireless interference, or a number of other causes. It is often suggested that users configure an AirPort base station while connected to it with an Ethernet cable to avoid confusion.
Sometimes it's easiest to start simple - give your AirPort network a short and simple name, no security, and no oddball settings like hiding its SSID. Make sure all your devices can join that network. Then, configure it with the wireless security appropriate for your devices, and go from there.
