I'm not very familiar with Mitsubishi, but there's one thing you can do to try to debug this one.

The program transfer is most likely done via FTP.
因此,使用一个免费的software like FileZilla for example, you can try to load the program manually.
If you can do it manually, we can help you figure out why the driver doesn't do it.
If you can't, this means a setting on the controller might prevent the transfer.

Yes the controller is preventing the transfer of files. I will try to find a solution.
