Late reply, so you may already have solved your issue, but check in Device Manager what COM ports your Moonlanders use.

In the start bat-file, change -S MLD:all (this means that all usb/com-ports are scanned for a miner)
to -S \\.\COM1 -S \\.\COM2 -S \\.\COM4 -S \\.\COM5 (this example is not scanning COM3, but 1,2,4 and 5)

I'm not sure if there is a delimiter to use... like -S \\.\COM1,\\.\COM2,\\.\COM4,\\.\COM5 so try the above method.

Hash away and good luck
