I've been trying to watch a movie that I downloaded and 1 of 2 things happen each time I try to cast it to my T.V.

1. It tells me it can't find a chromecast, and asks if it is connected to wifi (it is).
   It tells me that I need to try and uninstall the videostream thing and something else, but I have
   no clue how to do that because I just suck at all this technology stuff.

2. It will let me cast it to my T.V. but it buffers for a second and then goes to the black screen
   with the Videostream logo on it and tells me to come to this website for support.

Also, it is pretty terrible about freezing up during movies and stuff. I have perfect wifi signal, and if there is a way to fix it, please help! Thanks!
