How do I regain communication with WLCM in a 2821?

I was trying to get this running and had gone through the wizard for the basic config and could session to the controller before discovering the IP addressing I used was in the wrong MPLS VRF. I did a clear config and reset system, save: no.

Even putting the IP I originally used back on int in1/0 I cannot session to the controller module.

router-mpls#service-module Integrated-Service-Engine 1/0 session

Trying **.*.*.***, 2066 ...

% Connection refused by remote host

I have not reloaded the 2821 except that is did crash & reload on its own during this. A scheduled reload will take a figurative act of congress to approve.

ROM: System Bootstrap, Version 12.4(13r)T, RELEASE SOFTWARE (fc1)

router-mpls uptime is 1 day, 18 hours, 18 minutes

System returned to ROM by error - an Illegal Opcode exception, PC 0x8CA1E1AC at 15:13:30 MDT Tue Sep 8 2009

System restarted at 15:15:50 MDT Tue Sep 8 2009

System image file is "flash:/c2800nm-advipservicesk9-mz.124-22.T.bin"

Any suggestions?
