None off the plugins works

Hello all,

I am a user of showtime mediaplayer on the ps3 a while now.

Mostly im watching movies i put on a external harddrive and that works like a charm for me. But when i want to stream a movie within any available plugin i get an error like "unable to open resource". Why is that? Do i do something wrong? How can i fix this problem? Im on the latest version by the way and al the plugins are also updated,
