SEPM V12.1 - Cannot login to the admin account

Hi, could someone please help me with logging into the SEPM Console V12.1.  I think I have the correct password, but I cannot login to the SEPM Console.  I get the, "The administrator's user name or password is incorrect".   Unfortunately, we upgraded to V12.1, so there is no 'resetpass.bat' file to click on to reset it.  Also I cannot select the 'Forgot your password?' link since this was not setup.

Thanks,

Carl
