Plex permissions?

Hello once again good people of QuickBox.

I have a small problem and one questions.

I’ve had since the install a problem with plex writing permissions. I am trying to use a sub-zero subtitles downloader, but if often cannot write the files due to an error that it doesn’t have permission to write to the folders.

Anyone had this problem?

And the other thing, as I see, the updated version for me is 2.5.3 and was 2.5.3 when I checked the website, but now i only see 2.5.2?
