outlook express v6 to v5 mail moving problem

i've got outlook 6 on win xp on one computer and outlook 5 on win98 on another computer.

I tried copying inbox.dbx and sent items.dbx from outlook 6 and overwriting the ones in outlook 5. Restarted outlook 5, and it just created an inbox(1).dbx it didn't read the messages in inbox.dbx

I tried importing messages to OE5 doing an file..import and pointed it to inbox.dbx, that didn't work.

I tried copying over a load of dbx files, including folders.dbx, but the copying over of folders.dbx caused an msimn.exe crash, so I deleted the folder and restarted outlook express.

I gave up exporting messages. So onto exporting account details:

Then I tried exporting the account details tools..account..export-import (to save the time of typing them in). I exported them from OE6 and tried to import them to OE5. OE5 claimed to have imported them successfully, but clearly didn't. (nothing was listed under accounts).

I could read the dbx files with one of those OE save your email dbx reading programs, but I want to read them in outlook express. and of course I could type in the account details instead of importing them.

So, judging by the above, I think I've followed so i can't see why it hasn't worked for me

thanks in advance.
