How can I start over?

[J. David Beutel]

I've built and installed GnuCash 2.0.1 from source on Fedora Core 3, and 
now I'd like to follow the tutorial in the guide, starting with the New 
Account Hierarchy Setup.  Unfortunately I tried an older version of 
GnuCash a few years ago, and now whenever I start 2.0.1, it complains 
that it can't find an old file I made then.  All four of the files I 
made then are on the 2.0.1 File menu, even though I moved those files 
and ~/.gnucash away.

How can I get GnuCash to forget that I ever ran it before, forget about 
those old files, and run the setup druid?  It installed in /usr/local. I 
tried erasing the FC3 RPM (gnucash-1.8.11 installed in /usr) but that 
had no effect.
