I'm running CRM 2011 and ADFS 2.0, so things may be a bit different for you, but...
Check for errors in the CRM server's application log. I have seen ID 1309 in the past when the ADFS server updates its own certificates and the new ones are not trusted by the CRM server. For sanity, you can also check the certs that ADFS is using by opening the ADFS management console on that server, expanding the Service node, then clicking on Certificates. Check the dates on all the certs there. If the token signing and token decrypting certs are new, I would guess that's your issue. If so, you'll need to import the new certs into the CRM server's store and restart IIS. Don't change anything in ADFS if you haven't set up IFD personally and know what you are doing. I would advise exploration at this point without any modifications.
