UC Certificate Stopped working after Upgrade

Ok I have upgraded Exchange to service pack three. However now my UC Certificate has stopped working all together.

1. Should I start from scratch and re generate them from godaddy.
2.  Should I try to re enable the UC Certificate using the following command ?

Enable-ExchangeCertificate -Thumbprint paste_thumbprint_here -Services "SMTP, IMAP, IIS"

My  problem here is I am unsure on the correct thumbprint as I get the following when I run

Thumbprint                                Services   Subject
----------                                --------   -------

I am learning towards starting over on the UC Certificate but I really don't know what option to try.  Any advice would be great,

When you open outlook, do you get a security warning message ? when you click view the certificate, id it the correct certificate ?

Also, check the Certificate store on exchange server from MMC. do you have the correct certificate stored there ? if so, just re-assign services to certificate and restart exchange services.

Enable-ExchangeCertificate -thumbprint <certificate-thumbprint> -services "IIS,POP,IMAP"

Use the Get-ExchangeCertificate cmdlet to determine the thumbprint for your certificate.

-Open IIS Manager > Click On Server Name> Right Hand Windows you will find Server Certificates

> Double Click Server Certificate

> Over there you will find all the certificates.

>There will be certificate from the GoDaddy...Double clik on it

> Go to Details Tab ....over there you will find the ThumbPrint
