We just find your site because we have a data base that we want to repair but keeps show a System01.dbf error.

Following the steps in your post about this troublesome issue, we notice that the second screen after selecting the mode is not tha same as shown by your post. Your help in this matter will be appreciated.

It doesn't matter, for the document was written with old version software.

Please upload the prm.log or you can send me the whole database .
