I have the same problem besides the windows 10 1903 bug!
I got the same answer something like 4 or 5 days ago.
I am disappointed...
Thanks for the heads up! I was already using Airflow, it works like a charm, most of the time!!
I just tried the "chrome store" videostream app. It is working, but the subs are not loading, still...
What can I say...!
@Rockschuppen I am also a lifetime member. I also contacted them yesterday, for the third time, but still, no answer. Kind of strange since they answered quite fast the two previous times.
Anyway, I suggest we keep on "bothering" them, if you have not sent an email yet, please let them know that you are facing this problem and you want it solved soon (mail email@example.com)
Let's wait and see.
In the mean time, what are you doing as an alternative solution for streaming your content to chromecast?
Re: Videostream does not start after updating to Windows 10 1903
The same happens to me!
I contacted videostream yesterday and they told me that this is a known bug and that they are working on a solution.
I hope they will come up with something soon!!
There is nothing we can do at the moment, except from waiting or using another application of course!
