Microsoft Dynamics Connector AX and CRM

 Hello,

I have installed the dynamics connector for AX, but when I tried to configure the CRM 2011 adapter settings, the 'Object reference not set to an instance of an object' error occurs. The error occurs when I click ‘ Apply’ button. I also have attached the error log.

The following is the log from the Integration Client .log:

ERROR TID:1 [2013-01-15T17:01:38.4115307+07:00]: Unhandled exception. This may indicate a problem with the application but may not be fatal.
