Export problem

I've inherited an Oracle database that was recently upgraded from 7.0.15 to 7.1.5. When I try to do an export of the database I get the following error:
EXP-00037: Export views not compatible with database version EXP-00000: Export terminated unsuccessfully The version of Export is 7.1.5.2.4 which works fine with another 7.1.5 database I have. Can anyone tell me how to fix this problem?
