      Hello, I have some problem when I use "CyUSB.dll", when I run my app, the first run it, everything is ok, but for the second time, I got a message, I don't know what's that mean, could anyone help me fix it.

       

      I use .NET4.X,

      I don't program it By Visual Studio, It works fine when I develop and debug the device by Visual Studio.
