Hi, I have just fired up my Raspberry Pi, but am unable to get beyond the login stage. The system responds to my attempts with the message "Login Incorrect". The distribution/operating system is "Raspian" as supplied with the kit (pre loaded card). I have tried "root" as both the login and the password unsuccessfully, as well as the combinations of "rasberry" and "pi" as suggested on some forums that I have looked at, again without success. I don't think it is a power supply issue as the unit supplied is rated at 5V, 750ma, and the power checks out at approx, 5.1V across TP 1 and 2. I am an electronics engineer with over 35 years experience, but am not very computer/programming savvy (yet). Any help would be appreciated to get me going.
