user problem

Hello,

my sap license is expired and I want to renew it.So I logged on by SAP* and its password client 000.I logged on and want to SILENCE to extend the license.But an error has appeared that I can't modify sap license date using this SAP* user.I copied the user to new user and removed the user profile of SAP_ALL,then i tried to log on using the user SAP* and when I tried to use SU01 error no authorization .So how can i reset the SAP* to its default profile.

Regards,

Mohab
