[Zope] Recovering from Data.fs

Hi, I'm trying to recover a zope instance from a hardware failure. The only thing I have left is the backed up Data.fs file. I'm not entirely sure which version of Zope was used but I think it was 2.9 (certainly not 3), or what the install paths were for the instance or zope. When I try and use the backed Data.fs in a new zope instance I get the following error: Site Error An error was encountered while publishing this resource. Error Type: AttributeError Error Value: __getitem__

From my understanding the paths for the zope instance have to be the same for Data.fs to work correctly. Is that correct? If so how can I determine what version of zope was being used and what the paths were for the backed up Data.fs?

Thanks in advance, Rowan
