I would try the following:

1) Create a new, clean 2.9.x installation
2) Copy the Data.fs file (your 2.5.x version)

And see if it works. It could be that your non-root installation is messing 
things up.  If you have any ZCatalogs you will need to fix up the indexes 
(see the READMEs, there was some change in 2.6? 2.8? that requires a utility 
to update the indexes).
