Can not make any change inside ColdFusion 10 Admin

I installed 64-bit ColdFusion 10 on a  64-bit Windows 2008 R2 server.  I got error " There was an error accessing this page.  Check logs for more details." after I clicked "Submit Changes" when I tried to change JVM Heap Size, request tunning, setting up mail server, etc.  It doesn't let me to change anything.  I saw the following errors in the logs.

coldfusion-out.log:
