Cisco 2801 WAN DHCP Issues

I have a 2 part question. One I recently downgraded my offices service from Verizon Fios Static IP to Dynaic IP service because we no longer needed the Static IP. The service was witched over today and I thought I could simply log into the SDM web gui and change the wan to a dynamic dhcp. Unfortunately the router refuses to pick up the dynamic IP address. I can plug in a computer directly to the cable coming from verizon and get on to the internet. My computer finds the IP right away.

Second, I backed up the router config and wiped the router clean to see if that helped and it didn’t but now I can’t find an option in the SDM to upload a configuration file. How can I reload the config back onto the router?

I’m really in a pickle here.
