Your question was answered by support before you entered this in the Forum. But just incase others need to know of this issue we will allow it. The following is the resolution with 3Ware 3DM Utility.
In order to fix it, please go to GUI and in SETUP / SERVER
1. set proper time
2. set proper time zone
You must do both settings properly. If you skip time zone, so 3DM will NOT
work and prompt the error about cookies.
