Need help recovering from Assertion failed: 201819 invalid bitmap page

After a server crash and restoring his database (SQL Anywhere 9.0.2.2451), my customer gets the following:

Internal database error ***ERROR*** Assertion failed: 201819 (9.0.2.2451)

Checkpoint log:  invalid bitmap page -- transaction rolled back

SAP support is not available for this version.  I have worked through a document called "Database Recovery" and a document on recovering from assertion errors.  This error comes up immediately as you attempt to connect to the database.  There is no LOG file recovered.

Anybody know any magic that I could use to help my customer.

Thanks,

Bill
