IF SOMEBODY KNOW, WHAT`S THE SOLUTION, PLEASE SEND ME AN E-MAIL.

According to metalink:

ORA-1722 always occurs because of SQL problem. Check for the followings:

1, The syntax of the query.

2, Check for data type conversion and make values passed to functions
have the
right data type.

So, I first check to make sure that the export completed sucessfully. Then, if the export file was ftp'd, redo the ftp making sure you ftp binary.
