Need help with corrupted Oracle Datapump export

I have a corrupted Datapump export (Oracle 11g).   How do I use your tool to extract 2 tables from it?

I have downloaded DUL4108.

feedback:

 We can provide a data recovery service for  corrupted Datapump export. For extract data from datapump is not a packaged function in PRM-DUL 4108 .

 We wonder what about the export size  , can you pls send us the datapump file?
