[Zope] Please Help!

Hello All,

After renaming 3 folders within my zope site, I now when accessing the
management screen I receive the error:


An error has encountered while publishing this resource. 
struct.error
Sorry, a Zope error occurred. 
Traceback (innermost last):

  File D:\Zope2\lib\python\ZODB\FileStorage.py, line 443, in _load
    (Object: D:\Zope2/var/Data.fs)
error: unpack str size does not match format


Has anyone encountered this error before? Were they able to rectify this
problem?

Please help.

Regards,

Michael.
