could not register the window class

[hahac_299066]

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.

Dear,

you can check the attached file

void Start() works when the app first run

other code you just have a quick look.

When I fist run, everything works fine, but the second time or third time, there is an error as I mentioned.
