HiI was facing a similar issue...Have you tried nlserver config
-reloadIf you are getting an error here (as we got), this may be the
root cause of not being able to start the AC service.Check if there is
an existing 'diff' file in your conf folder.Rename it (i.e. change the
externsion to '.diff_old').Re try the nlserver config -reloadAnd try
again to start the service.It should work now (it worked for us).Regards
