Sybase SQL Backup Problems

[Pahlay]

I am trying to backup a Sybase SQL dbase from Sybase Central. I have not previously used Sybase. When I attempt to run the backup I get the following error:

java.sql.SQLException: [Sybase][ODBC Driver][SQL Anywhere]Could not load the backup/restore DLL "libsybbr.dll"

Thanks for your help.
