From your cry for help, it appears you did not create a back up of your
database?
What do you mean by 'setup security settings in my database and deleted
same'? What did you delete?
You may have to ensure you are joined to the System.mdw file that comes with
Access and not the mdw file that you may have created when creating your
security settings. If you created the security settings over the original
System.mdw file that comes with Access, then you may have just hosed
yourself.
Can you give us your step by step actions? Then we can better tell you how
to recover, if possible.
