Ok Guys I may be onto something here, if your using an android, and want to use STB PRO Emulator, I have the fix, Its more stable and a lot less buggier, First of all you need to download the .apk in from,
Code:
https://mega.nz/#!nAxl1RTK!Wn0GbxnDRJwv1fQ87Uk6IUgc_yEKzOQYlqljNBLv5Fw
Then After You Download, the PRO Version, you need to Download the x86 or Arm7 From, x86 Download link,
Code:

&
Arm7 link
Code:
https://mega.nz/#!CQwEGDJB!-xc3Gfwxx4UWx5mEQ1AEX5ZIsUvHCLNqgY-UHe7r34U
Once you downloaded the x86 or Arm7 STB Emulator IPTV, then you must install the version you want, after installing you want to goto Profiles, then NFPS, then Serial Number, this is a generated ID, for your device, you must copy it down and save it for later, example my serial number starts with: bde9************ which should be 16 letters long, now go ahead and delete the Apk file/ IPTV STB Emulator you downloaded, and install the STB PRO Emulator from the link above, After installing, you must configure the profile to these settings, Bow604v.jpg and set your Serial number to the generated one that you wrote down, and finally set your Valid MAC Address, and a extra tip in the : Menu, click Media Player and click External Media Player, Exit, then re open and click MKV player if you have it installed, it works well, Hope this helps, please leave comments below!
