DR4100 failure writing to NVRAM

Hi Everyone,

We are currently having an issue with our DR 4100 appliance which went out of warranty last month where it's currently in Maintenance mode showing the following error message

Failure writing to NVRAM. Error - c00000020000000c.

We are trying to contact Support via phone but none of the numbers we have are working. (Either no one picks it up or busy tone)

Could anyone please advise how we can get in contact with Support or at least how we can download latest firmware for this appliance from the following link?


Thanks in advance
