Bull_Auger,
I believe the best aim for support is to contact OneCare support. Do to the nature of your issue surrounding Administrator Rights when you are the Administrator. If you have a paid subscription, you should be able to get telephone help.

You can also click the link above to start the support flow directly if OneCare cannot start or if you are at a PC where OneCare is not installed.
If you click on "get more help" in the lower right and then "Get support", you will be brought to a page where you will be able to select Billing Support or Technical Support and be walked through a wizard that requires you to log in with your LiveID and will attempt to validate your subscription if you select that the problem is on "this computer."
This allows the system to provide you with access to email, chat or phone support information , depending on your subscription status. If you are a trial user, you will only have access to email support and should select that option during the flow.
-----------------------------------------
** Note that if the flow cannot validate your subscription status - legitimately or otherwise, then select the option that you are a "trial or beta" user and proceed to the email support form. Provide as much information as possible, including the fact that you are a paid subscriber and wish to proceed with support via phone or chat.
I hope this information helps.
