no access to Sync settings

[cdsuggs]

The contacts and calendar from my MBP are not syncing to MobileMe.

System Preferences > MobileMe > Sync

When I select the Sync button, it highlights but the options do not display. Also, the icon in the Menu Bar is not responding to me.

Here's what I've checked
- user account is admin
- login address is @me.com
- have restarted and shut down several times

Seems to pertain only to my log-in. Other log-ins on this machine seem okay but I'm hesitant to log into my MobileMe for fear of jacking up my data.

Any ideas as to what's preventing me from accessing the settings?

Thanks,
Chris
