Reset Trend Micro OfficeScan Console

After given the password to access Trend Micro Office Console to the headquater in US, I'm having problem signing in.

Using OfficeScan 8 Service Pack 1 Build 3243 .
To reset the password :

Edit \Program Files\Trend Micro\OfficeScan\PCCSRV\ofscan.ini
Change the section, master_pwd= value to = 70 & save it.

Edit \Program Files\Trend Micro\OfficeScan\PCCSRV\Private\ofcserver.ini
Change master_pwd= value to 70 & save it.

Sign in to console using default password -> 1

I wonder what the fella in US is trying to do with my OfficeScan.
