Note: [Urgent] is generally not a good way to escalate the issue on a
public mailing list. We're all here for the fun of it and demanding
prompt reply may actually serve the other way.
If you have paid to get support (e.g: by buying hardware), this may be a
good time to use it.
That said, your message looks interesting. So see my reply inline :-)

You probably needed 'module unload chan_zap.so' before that. The module
was loaded, but it has bailed out before registering the CLI commands.

The symptom is expelained in the following report that I filed earlier
today (unrelated to this one)
http://bugs.digium.com/12071
Channel 1 was left open from a failed configuration attempt
So the real error hides earlier in your logs. Look for 'chan_zap' in the
logs from the startup of Asterisk. And sadly you must restart Asterisk
to fix the error.

Is this a fractional E1, indeed?
Or is the range in zaptel.conf incorrect? I noticed in your config file
that you changed it. Was this change made after Asterisk was started?

I'm not sure how an Astribank module would have affected this one. The
Astribank spans tend to be the last ones, hence it should not have
misplaced your hardware.
If the module is loaded but no hardware is present, your system should
not be affected.
