Seem to have lost the default User ID for the administrator. How do I get it back.

When I sign in as Sys with password sys I get the following message:
Caution: signon failed!

Help

Hi SChis,

Something has probably changed in the Adagio user security file. Or perhaps the password for this user has been changed. But we cannot post technical information regarding the location or editing or resetting this file. This situation is best resolved with your Adagio consultant.
