[ms_access] Unprotect a base

[Ove Billing]

I have protected an Access 2000 (Swedish ed) base with three levels or
groups (admin, feed new data and just look). I used the wizard (Tools,
Security) but now I want the undo the locking by using the wizard (I
checked to change the existing security file, unchecked all items now
protected) but the opening still requires the keys to allow opening.
How do I get the virgin base back? (I want to use it as a template for
a new base).
I hope this is the proper group to use for such a question. /Ove
