#1 WriteRead causing NullReferenceException

[Adam Demasi]

I am using this library with a Visual Basic.NET 2010 and everything is working until I need to use WriteRead.

My code is:

Dim response() As Byte = prog.WriteRead(16, {&H76, 90, 90, 90, 90, 90, 90, 90})

And it gives me a NullReferenceException, saying that the array of data should be used with the New keyword, or by checking that it is not Nothing. I tried doing both and they didn't work.
Am I doing something wrong here? Thanks in advance.
