Windows Mobile Device Center Calendar Sync Error

Hello,

I'm always having trouble with synchronizing my Calendar items. Everytime I
try to select the Calendars to sync for more than the default 2 weeks I get
an error dialog box saying:

"Unhandled exception has occurred in your application. If you click
Continue, the application will ignore this error and attempt to continue. If
you click Quit, the application will close immediately.

Object reference not set to an instance of an object."

When you click on details this shows:

"See the end of this message for details on invoking
just-in-time (JIT) debugging instead of this dialog box.

************** Exception Text **************
System.NullReferenceException: Object reference not set to an instance of an
object.

************** JIT Debugging **************
To enable just-in-time (JIT) debugging, the .config file for this
application or computer (machine.config) must have the
jitDebugging value set in the system.windows.forms section.
The application must also be compiled with debugging
enabled.

For example:

<configuration>
<system.windows.forms jitDebugging="true" />
</configuration>

When JIT debugging is enabled, any unhandled exception
will be sent to the JIT debugger registered on the computer
rather than be handled by this dialog box."

Has anyone else had this issue? Also it doesn't allow me to sync other
applications that I could in Windows XP. I'm using Windows Vista RC1 Build
5600. Can anyone help me with this? Thanks.
