Synology DS213j and shared folders

Hi guys,
first of all, sorry for my bad english, Iam from Germany and i have following problems.
I Installed on my DS213j (ARM CPU) serviio and the serviio console (after installing java etc.). It works in that way, that I can get access to the serviio media server via my TV.
The problem is, that I cannot get any folders to shared folders. I dont have the button "Add patch". I only have the button "Add local". I even tried to get it via ftp (online source) but it is not able to safe because of error 503 (not able to save).
Do you know what I have to do, to get the "add path" button or any other way to get folders to the library?
thanks for help
