USB Communication error with 33522A

I have downloaded a Agilent benchlink builder software in order to communicate from my PC to 33522A with USB interface. My device is connected and I can send commands following Agilent interactive I/O. I have seen demo on youtube but in spite of instructions, I have an unspecified error:

Object reference not set to an instance of an object.
Please provide the information below to Agilent technologies
   at Agilent.Wfe.Gui.SendToInstrDlg.Dispose(Boolean disposing)
   at System.ComponentModel.Component.Finalize()

So I can't directly send a .arb (attached file Double_pulse.arb) file from the builder software to 33522A.

However, I can load this file according to USB stick, in 33522A without communications problems. It's a good solution but in my application I'd rather directly send data to my instrument from the builder.

Can you help me about error message and the procedure?

Best regards
