Same here. I updated the Now tv app last night and now i just get the "took too long to open" error, uninstalled and reinstalled app, even formatted the xbox with still no joy. Xbox is fully updated, the only issue it think it could be is that the xbox is on the insider programm so gets preview builds. But even if this is the case both Ms and Nowtv should have tested this before relasing it, Getting frustrstrated as ive just cancelled virgin tv in fav of now tv
If you are experiencing this issue please can you do the following :
Hold down the power button until your machine turns off then restart your Xbox 360.
You may have to do this several times until the app works again.
Also if you have your Xbox set to Quick Boot Mode this could also be contributing to the error message as your Xbox doesn't fully turn off, try disabling this mode and follow the above procedure.
Please note if you are on the Xbox One preview program we cannot explicitly support users who are on this as this also may be creating the error.
Our teams are continuing to look into the issue however we are not the only app that has been affected by the latest update to the Xbox One.
The NOW TV Team.
I'm having exactly the same issue. It was working fine this morning, then there was a console update and now it won't launch, just comes up with the "taken too long to start" error code.
I'm in the preview program.
I've tried several suggestions but nothing has worked so far 😞
Come back Now TV, I miss you!
