E111 existence of directory

Yeah, you really need to update FSF. We've had some strange issues because
we were using a version of FSF that was created long before the version of
eDirectory that's in use.

And it's probably hit or miss if your cleanup on those files will go
smoothly. Do you have upgrade/maintenance/whatever-it's-called-these-days
on FSF? If you do, then you should have access to NSM code and licenses
via your customer care portal.
