Hi
I can see an exception when EV tries to load the hidden settings mail:

Did you have any customizations for EV in the OWA web.config?
They get lost when upgrading a Service Pack.
Could you restore your previous web.config, and insert all customized EV values from there into the new web.config and try again?
Cheers
