Fix config manager to show errors

If there were fatal bugs in this portion of config, they would never be displayed
because config would fail to load and then every^U (Exageration... only
half of every) other part of the code which depended on config to be
loaded would fail before we ever got around to a section of code that
would process UNABLE.

Remove the try except from here so that we are able to debug this code
