Here's what probably happened:

1) The database was created with IB 5, so it was ODS 9.
2) They upgraded to IB 6 / Firebird, which can read not ODS 9 and ODS 10
databases.
3) They did a backup and restored the database with IB 6, which converted it to
ODS 10.
4) They re-installed your app, which brought them back to IB 5, which can not
read ODS 10 databases.

Baiscally, they will need to upgrade to IB 6 / Firebird again.
