I would recommend contacting support, if removing InCD didn't resolve it. On the other hand, there is another Nero component that has been known to cause conflicts - sorry for not recalling the name, but it a module that handles launching Nero programs based on the detection of media in the drives.
Is this the beta 2.0? If so, support for 2.0 Beta - http://help.live.com/help.aspx?project=onecarev2 - use the "Get More Help" link in the lower right of the page to contact support via email.
