Purchased CWP Pro - Attempting to activate it breaks CWP.

Recently purchased CWP Pro, installed on a dedicated box with a /29 IP block assigned.  Everything works, nameservers set, content migrated over and everything is ready to go.

Attempted to run cwp_update to force Pro to activate, which resulted in errors, and CWP failing to start/restart/function in general. 

# sh /scripts/update_cwp

After running this command, the server will no longer ping domains, load CWP, or perform much at all.  I can still ping IP's however.

# ping google.com
ping: google.com: Name or service not known

# ping 8.8.8.8
PING 8.8.8.8 (8.8.8. 56(84) bytes of data.
64 bytes from 8.8.8.8: icmp_seq=1 ttl=58 time=15.9 ms
64 bytes from 8.8.8.8: icmp_seq=2 ttl=58 time=15.9 ms

Very confused on how the included instructions for activating CWP Pro could end up breaking an entire installation.

I have same/ similar problem...
