Help with connecting in multi player mode

[SadlerSailing]

I need a little help connecting to multi player VSK5
Everything has been working fine until a few days ago, now I can not use the multi player mode.
I keep getting a message " COULD NOT INIT THE NETWORK"

Can anyone point me in the right direction please.

I have not changed anything that I know of since the last time I was online a week or so ago.

Nige.
