Frozen screen on MFD a125

Hi

Trying to connect to our Marina network, it froze the screen and I cannot do anything.

The error message I am getting on the screen:

"Unable to connect
has issued an IP address which conflicts with your Raymarine network 10.20.14.49
Please change the access point settings or contact the network administrator"

I have been in contact with 2 Raymarine support persons:
1. Unplug and plug back the power: didn't do anything
2. Reset the system: did it but didn't help

Did anybody had a similar experience?

Thanks!
