Tried to open a configurator encoded file with Correlant's
DOCSIS 1.1 config file editor and it reported both cmts
and cm MIC errors.
the keyfile did contain the correct shared secret.

If you are using Win32 version of configurator it could be
the effect of a bug described in "Request ID 914121". The
problem described in that request seems to remain in version
0.9.1 of the configurator.
You can find a patch in "Patches" section.
Without more information, this is going to be very difficult to fix. If this is still an issue, do you have sample config files that exhibit the problem?
