Get error "There was a problem installing the update:

I get the following error when trying to update my plex server:

File sha1 mismatch, can't patch:/var/folders/6q/tyxqng_n5j9rcspgiz9r8280000gn/T/plexUpdater.V.Jpi5t/Plex Media Server.app/Contents/Frameworks/Growl.framework/Versions/A/Growl

Any ideas on how to resolve?

Thanks,
