Deleting the config value from Moodle shouldn't be too hard , or dangerous. If it doesn't work at the moment you shouldn't lose anything anyway.
Might be an idea though, rather than to delete the entry from the config table, just rename the field to have _old or _broken at the end or similar.
Hope that helps!
did you notice the manual to setup a mahoodle combo:

I have read other posts that talk about deleting a reference in the mdl-config file, regenerating the ‘mnet’ value, etc, but this sounds a bit dangerous. Does anybody have any other suggestions?
Thanks
