Problem setting up DNS

[Sdävtaker]

Hello, im using FBSD 6.2

I got 2 domains registered in the local nic and I could get one working 
but the second one doesnt :-/
This is my first attemp to set up a real DNS, so im pretty sure i did 
something wrong, i copy/pasted here all the info i think can be usefull, 
i can add more data if necesary.
BTW, sorry for my english, it is not my main language.
Thanks for any help.

Info:

I got this in named.conf:
(...)
zone "unhost.com.ar" {
     type master;
     file "master/unhost.com.ar";
	allow-transfer {
     202.157.182.142;
     };
};

zone "sacrarium.com.ar" {
     type master;
     file "master/sacrarium.com.ar";
     allow-transfer {
	202.157.182.142;
     };
};
(...)

The first one is working the second one is not.
In nic.ar both point to ns1.unhost.com.ar and 202.157.182.142 
(twisted4life free secondary)

the Zone files are:
master/unhost.com.ar:
$TTL 86400        ; 1 day
unhost.com.ar.    IN      SOA      ns1.unhost.com.ar. admin.unhost.com.ar. (

                                 10800           ; Refresh
                                 3600            ; Retry
                                 604800          ; Expire
                                 86400           ; Minimum TTL
                         )
