SOE Updates: How to update Interface

[Stabo]

I'm non-technical, so I may be asking a simple question. I've spent a little time looking around for threads on Updates, but most everything I find is geared to initial installation.

I'm currently using Fetish Nightfall and love it.

Anyway, do I need to reinstall the interface with each SOE Update once an update compliant version of the FN Interface is available? Uninstall/Reinstall or is there another proceedure for installing updated versions/patches.

OR

Does the Interface "auto-update" once a newer update compliant version is released?

Of course I'm hoping the latter case to be true. If not I'll look around for instructions on Updating Interfaces.

Thanks.
