Hi,
first, I would suggest you to use VMWare ESXi Server (free) for your testing, as VMWare Workstation is not supported by SBG.
Also, you can check the BrightmailLog.log file after you try to start the Controlcenter service, in order to find the reason why it's not starting.
Tip: open a second command line prompt on the appliance (as "admin" user), then type "watch BrightmailLog.log" to see realtime logging of controlcenter.
KInd Regards
