Sybase Central - The Service xxx has generated an unknown error

Customer using Sybase SQL Anywhere 11 was hacked and we have gotten them back up.

We are getting "Sybase Central - The Service xxx has generated an unknown error" when attempting to start service using Sybase Central.
Have also attempted to start via windows services and service starts and immediately stops
Application log entry shows "Could not start server" keyword 0x80000000000000

Service Properties are:
C:\Program Files\SQL Anywhere 11\Bin32\dbsrv11.exe
parms:  -o c:\agricom\sql11.log -n sam C:\agricom\sam\samsb.db -c 500m -x tcpip
Local Account, service is NOT allowed to interact with desktop
Have tried with/without "This service belongs to a service group"
No polling

Have dropped service and recreated but same error

Database starts okay via ODBC using Central or ISQL
