Compliance Accelerator Cannot Connect to server

I upated Enterprise Vault 9.0 to 9.0 SP4 last night. I then updated Compliance accelerator as well. Now when I try to login from the Compliance Accelerator Client I receive a message that says "Cannot connect to server - The server is in the process of being upgraded, please try again later." I rebooted the EV servers and that didn't have any effect. Any ideas as what's causing the issue? All the services are running and when I login to Enterprise Vault it shows that it's been updated to the latest version.
