iptv66, some channels play but most don't on my fire stick using stb emulator

hey guys,

anyone know what the issue could be here, some of the channels play but most don't. i select the channel and nothing just a black screen..... anyone had this happen before?


tried the account on a fire tv box with working package and had the same issues, also the VOD doesn't select and play anything. I think there is a problem with the way it was setup. how do i go about getting this corrected.
 
I had this problem today using the latest version of STB Emulator. I uninstallled it and installed this version(stbemu-nfps-armv7-release-0.7.06.01.apk).
I don't know why but the latest version (stbemu-googleplay-armv7-release-0.8.apk) did not work for me. No channels opened all stayed on a black screen.
I uninstalled it and installed the older version and all the channels worked.
