acapellas4U - 'gonefishin'

I dont know if anyone uses acapellas4u.co.uk (chances are no!), but this is my desperate attempt to find a Moss or Roy out there to help me (The IT Crowd). When I go to register, it shows general error gonefishin. Does anyone know what the problem is? I know I am being slightly naive in thinking that someone is going to give me the answer but I thought it was worth a go.

Everything is always worth a go, young lady.

Probably either means that they've been hacked into, or that they've closed registrations for some reason, and put that up as a message.
