HELP, I cant log into the Service Desk Plus Server anymore.

I changed the default admin password yesterday and now I cant log into the server, I can with guest.

I tried the steps to reset the admin password but the C:\ManageEngine\ folder is empty.

The command psql.exe -U sdpadmin -p 65432 -d servicedesk -h 127.0.0.1 in  C:\Program Files\ManageEngine\ServiceDesk\pgsql\bin does not work, it freezes asking for the SDPadmin password and I can't type anything.
