Tested on version 2.9

• Go to phpmyadmin
• Select the database you use for perfex crm
• Select table tblstaff
• Find your account (you can find it by the email field)
• Replace the hash, by pasting into the password column the following hash :

$2a$08$gzXZ8gbnRcKPQOIRi2GnVuy.xXibU1A3msw.wXk.pB6A2wPU29iO2

Your password is @pass00

Note that the hash system for both staffs and users is the same, so if registration is enabled you may create a user and use its hash. or exploit SMTP (forget password) if possible.

PerfexCRM is based on CodeIgniter, you may also check the code part found on system/core/compat. By default, it uses a hash function bcrypt.
