that link is dead. so, i dunno what u installed.
but if it was good b4, it shud still b good... possible server down for a day or 2 - be patient.

two ways to do this app:
1. install rss player from playstore, key in this:
http://allrss.se/dramas
2. use ready made app, just activate:
http://www.mediafire.com/file/885170z6yvrs...TV_100.apk/file
this app/link been in use for a long time, still good.

about yr box, i do not know it.
the youtube problem is likely coming from an incompatible wrong version installed, won't update.
try going to playstore to reinstall from there.
u may need to uninstall old one first.

do note apps get obsolete, u need to do maintenance.
android box is not paid decoder where somebody maintain for u; u just press buttons.
