We were all new once. What your going to have to do is play catch up. Reading around this board will tell you a lot and reading the BOINC program help files should help some more. Explore and reading around the seti web site is also useful as others may have this problem. Sorry, but the information you supplied is way to little to provide any help, and a password word problem could be anything from a typo to a major software bug, not unlikley with BOINC's on going development .
Good luck
