As a new user I was dismayed when i was "locked" out of my main file. I
tried all the solution suggestions that google brought up with no luck. The
website seemed to be unavailable.  The manual was no help. I subscribed to
this group, as it was said to be the best place to get help. Eventually I
just wandered around looking at all the gnucash files (this particular
thread did not yet exist.) After reinstalling the program for the umpteenth
time, instead of trying to open a file through the program, I just accessed
the file directly.  Voila, success. No further problems.  Still don't
understand what caused the issue, just glad I can carry on. And yes, I do
regular backups to a separate hard drive.
