Problem on Arbexpress

[WasabiSC]

Good morning/afternoon to everyone,
I'm a newbie to this forum so sorry if the question I'm gonna be asking will be bad, anyway I have this problem:

I am currently using a Tektronics AFG31052 to generate 2 square wave signals (with changing phase and frequency). To do that I have done a small script in Matlab to generate to 'txt' files to plug in Arbexpress and convert them into 'tfwx' format, then by using a usb stick I get the desired signals and thats easy.

What I had in mind was to use the LAN connection to output the signals without going thorugh the USB stick (and maybe not even Arbexpress), I have connected "successfully" my PC to the AFG: I am able to generate simple signals through the Instrument control, but I cant send any file to the AFG nor I can see the Instrument folders. To be more precise when I try to send via File transfer I have the error shown in attachment.

So what Im asking is what Im doing wrong here?

SOLVED

To correct this problem just uninstal and reinstall the version of Arbexpress used or perform a downgrade.
