Site to site VPN not working between ASA 5505 and 5510

I have an ASA 5505 and a 5510 that had a VPN connection working until the external ip address of the 5510 changed. I deleted the existing VPN connection on the 5505 and recrerated it with the new address of the 5510. I can see that the vpn lin is established, but the 5505 isn't transmitting any bytes. I looked in the Monitoring > VPN > VPN Statistics > Sessions and I see that the link is established and the bytes Rx is working, but the bytes Tx stays at 0 (this is on the 5505, on the 5510 there are no Bytes Rx, but there are bytes Tx). I don't think the problem is with the 5510, because that router has a vpn connection to another 5505 which is working fine.

Here is the config for the 5505 where the VPN isn't working: The VPN in question is the one with the ip address 207.229.xx.xx the other VPN (208.118.xx.xx is working, but is no longer needed)

Result of the command: "show running-config"

Site to site VPN not working between ASA 5505 and 5510

Nevermind I got it. I deleted the site to site profile and and crypto map/acl entry associated with it then recreated the vpn profile and it is working now.
