keylogger crack password

[hatethis]

I'm using eblaster keylogger and received keystrokes with login to yahoo. When I tried to login using the password captured yahoo gives me an error "invalid". Other keystrokes captured have worked fine. Does anyone have any idea what might be causing this?

Keyboard hardware: Hardware keyloggers are used for keystroke logging by means of a hardware circuit that is attached somewhere in between the computer keyboard and the computer,HP2-E13 (http://www.testking.net/testking-HP2-E13.htm) typically inline with the keyboard's cable connector. More stealthy implementations can be installed or built into standard keyboards, so that no device is visible on the external cable. Both types log all keyboard activity to their internal memory,642-873 (http://www.testking.net/testking-642-873.htm) which can be subsequently accessed, for example, by typing in a secret key sequence.A hardware keylogger has an advantage over a software solution: it is not dependent on being installed on the target computer's operating system and therefore will not interfere with any program running on the target machine or be detected by any software. However its physical presence may be detected if,642-415 (http://www.testking.net/testking-642-415.htm) for example, it is installed outside the case as an inline device between the computer and the keyboard. Some of these implementations have the ability to be controlled and monitored remotely by means of a wireless communication standard.
