Cannot donwload Code to LEGO Cybermaster Unit

Hello,

I hope there is someone out there to help me. It's a bit of an exotic issiue.

Actually I don't know if thats the right Forum for my request. Maybe there's an Admin who knows where this thread would better fit in.

I recently dug out my old LEGO cybermaster set and tried to make it work.

I wanted to show my son (5 years old) the fantastic world of Lego Cybermaster.
So I set up a VM (VirtualBox) with windows XP and installed the Cybermaster software there. Everything's runnung greatly. (If someone is interested I'd love to share the setup process).
I can start the software and get a connection in game between the tower unit and the mobile unit. I connected the Tower Unit through a Serial-USB Connector with the PC (its a windows surface 4pro by the way).
It takes some time to connect, but it always will (I assume it's due to the VM).
In Game I can controll the Mobile unit directly with arrow keys and the additional motor with CTRL and ALT. No Problem.

My Son and I having already a great time with the set. So it was already worth it.

PROBLEM: I cannot download a Program (Code) to the mobile unit. When I try, the Tower starts flickering as well as the mobile unit, but after a few seconds the mobile unit just turns off. No Programm downloaded.

I also installde Bricx Command Center directly in Windows 10. Here the connection starts immediately. I, again, have direct control via the "Brick Joystick" Tool and the "Direct Control" Tool.
I cann also play music notes through the "Brick Piano". But still I cannot download code to the Mobile Unit.
I can write code and compile ist successfully, but the download always crashes.

I own three Mobile units (and Towers) now for testing. All show the same behavior.
I assume it's got something to do with the Serial Connector. Maybe the Read and Writing timings are off. But i have no idea what to change them to.

I hope someone here can help me. I'd really love to show my son how we can program the robot to do what we want.

Thank you very much.
