Export fnd_user synonym

[fadalji]

We took a clone of HRMS 11.5.10.2, on 9.2.0 Database for TESTing purposes, upgraded to DB 10.2.0, accessed apps successfully, plus applied some patches, and have been unale to access apps since. fixed a number of mistakes, and now the fnd_user table does not have any data in it. now the fnd_user is a synonym, and we'd like to know what is the best way for us to export data from PRODUCTION to TEST?
Your Advice will be invaluable.

Ohhh some background behind this, I can't log into apps, b/c user info is kept in this table, so my guest user name and data is kept here, and I need this data available in FND_USER before I can login to E-business Suites
