[analizer3816]

I have iphone 5s and iPad3, I can install B4i-bridge on both last month.
But today I can't. no any error in b4i.
I install b4i-bridge from 63.135.170.51:51041, devices show dialog "cannot install app, retry..."
then I try install my app by run in debug mode and click link on 63.135.170.51:51041 for installing,
I can install and run it.
how do I fix ?
thanks
