[Zope] ZODB issues

I have installed a new instance of zope 2.7.4. I have brought in a 
Data.fs file from another ISP. I don't know exactly what version this 
file is from, but I am fairly sure its some 2.x version. My question(s) 
is what to do next, I am new to zope, but I have tried a lot of things. 
The basic problem is that the btree structure of the interesting part of 
the site is broken (perhaps corrupt).I can start and run the server, and 
browse through the control panel, and perform various administrative 
tasks. The top level index_html file is just a redirect to the site1 
folder structure, which is the one that is broken. I mention this, 
because this file works, but any contents below site1 are not visible.

this works
-su-2.05b$ python utilities/ZODBTools/fstest.py var/Data.fs
-su-2.05b$ python utilities/ZODBTools/fsrefs.py var/Data.fs
as does

-su-2.05b$ python utilities/ZODBTools/fsdump.py var/Data.fs | less


This doesn't

nor does this, but I also get this error on a Data.fs that is not 
broken, so I don't understand what I am doing wrong ?

-su-2.05b$ python lib/python/ZODB/fsrecover.py -P 1 -v 2 var/Data.fs
Traceback (most recent call last):
  File "lib/python/ZODB/fsrecover.py", line 374, in ?

    opts, (inp, outp) = getopt.getopt(sys.argv[1:], "fv:pP:")
ValueError: unpack list of wrong size


I attempted to try and follow the instructions to fix a corrupted 
database, but I got errors that
the root did not exist....

 >>> from Zope.Startup.run import configure
 >>> configure('/www/htdocs/esginc.com/zope/etc/zope.conf')
 >>> from ZODB.POSException import POSKeyError
 >>> obj=root.unrestrictedTraverse('/site1')
Traceback (most recent call last):
  File "<stdin>", line 1, in ?
NameError: name 'root' is not defined


It really sort of 'seems' like I have mounted the database incorrectly, 
and if I could fix some simple
mistake some where, ....

What I have done to import this Data.fs is to copy the file into var, 
delete the index, modify the zope.conf to be somewhat similar to the way 
it was in the 'other' server, and copy the files/contents of import
