smart iptv issue

Hello, I had to reset my Samsung Smart TV R Series and expectedly lost all my apps. I tried reinstalling the Smart IPTV app with the userwidget on my usb stick and I am getting this error message: [User App] ._SmartIPTV.tmg, invalid app package for security check failed! What can I do?

Hello, I have over 40 customers which are using Samsung SIPTV. At the moment I have to upload them the playlist nearly every day. All People are writing me that they have an CHECK URL Error. What's the problem guys? Is there a solution for that?
