It might be a problem in my pc, becuase I downloaded FDV file set from another PC and it is fine. I will redownload all the package and try again in other pc. I used WinXP with all patches to do the hfslip. I found another issue with my current hfslipped installation. I created two accounts while doing the installation: acctA, acctB, but when I start the system, and login in with any accoutn, there is no password needed. I have manually confige these two account to use password. Then I logged out, and click any of the account name, the passsword input edit box appeared, but couln't input anything in the box, there is no cursor in the box. then I pressed Ctrl-Alt-Del and get to classic login window, in where I can input password. and I logged in. Then I found out if I logout with switch user to other account, and Ctrl-Alt-Del and login, and logout with switch user, now I can input password in the password input box. after that the login window start working.
