After installing framework 4.0 on my CAS server on Sunday, my OWA instance is now broken. I turned custom errors = off to see what the error is and below is what is displayed. The upgrade also broke my custom code running on the CAS server. Any idea on how to get OWA back in working order? I just installed .Net Framework 4.0 from windows update and did not customize it in anyway.
