I downloaded the app on my iPad and tried to connect my windows share. It said that I need to upgrade it to pro version. I tried 2 to 3 times and got the same message. But then 1 more try gave me a message that i can get the pro version for free if I leave comment for the app. I did left comment and got pro version unlocked for free.
Please try it to get free pro version of PlayerXtream.
