I still have the problem and tried different installs. If I use the
2.5rc2 32 bit on my 64 bit Windows server I can open the old files.

If I use the 2.5rc2 64 bit edition, opening old files is not possible.
It only works with backup restore.

I noticed the same problem with FB 2.1.

So FDB files from 32bit and 64 bit edtions are not compatible.
