checkzone is telling you where the problem is: it's on line 37 of that
file. Furthermore, the zone is not being loaded because it's erroneous.

> www.espersunited.com.		IN A 192.168.0.2
[...]

> www.espersunited.com.           IN CNAME carter.espersunited.com.

You have a CNAME for www and an A record for it; that's illegal, which
is why BIND is saying 'CNAME and other data'.
