RESTORE MAIL FROM AN OLD ''MAILSTORE'' BACKUP

I need to restore an old mailstore backup [login to view URL] either in outlook and with its own mailstore reader program. Mailstore version is the free one. I am not able to do it on my own as I think there is a version problems and need a small updates. - The DB and files will be on a dedicated pc remote desktop - you will access remotely (sys XP HOME) - you will work remotely (files are very heavy)
