Shibboleth SP error (2.5.3 latest)

One of our SPs (updated to the latest patch a couple of weeks ago) has a lot of this in the Event logs (Windows):
The description for Event ID 2100 from source OpenSAML XMLTooling Library cannot be found. Either the component that raises this event is not installed on your local computer or the installation is corrupted. You can install or repair the component on the local computer.

If the event originated on another computer, the display information had to be saved with the event.

The following information was included with the event:

error in file permissions or logging configuration: exception creating appender: failed to open log file (C:/opt/shibboleth-sp/var/log/shibboleth/native.log)

Any ideas? I would imagine that as the SP runs as a service it should be running as system which has no issues writing to the log file?
The last time the log file was updated was yesterday, and when I did a test hit of it just now it didn't write to native.log - but that may be normal behaviour.

We've been having the error for months it seems, before I ran the patch.
