I have a user who installed FtpVC and then promptly forgot what they typed for the password (there really is no hope sometimes) .
We have no way of finding out what it is and uninstalling the application and reinstalling doesn't help.
I assume that there are some hooks in the registry that need to be removed so that we can install a fresh copy, get him to remember the password and then register the software.
2) Try some other user name (FtpVC will ask you to set and confirm a new password). Then go back to your previous user name and set up a desired password.
