What error? www.gshock.co.uk is a cname for gshock.co.uk, as nslookup
has told you. It thus cannot have an MX record associated with it.

Sounds like you added the zone to named.conf but did not delegate it
from gshock.co.uk. Add an NS record for files.gshock.co.uk.
I do note that your two listed name servers report different serial
numbers for gshock.co.uk. You'll need to fix your delegation problems
before anything will work reliably.
