You need to login to the camera directly, can use your browser and just enter the IP address in the url address line on the browser. Hopefully you'll get a login prompt asking for the userid and password. If it still doesn't accept the password, then you'll have to hard reset the camera itself to go back to factory default settings and start over.
This has nothing to do with the HiP2P program; there is no password recover function on HiP2P. Get the password set correctly in the camera first, then come back to HiP2P program and update the password for your device.
