Error reading digitize data points with Polhemus

I managed to get the Polhemus device to communicate with Digitize now. It worked after I uninstalled and reinstalled the driver for the serial port via the Windows device manager. However, the EEG montage still looks strange. The channel names appear in strange characters (see screenshot below).

I loaded the montage from brainstorm3 > defaults > eeg > NotAligned and tried all versions of the channel_BioSemi_64 montage. The 10-10 version is the one I need.

Is that not the correct file to use?
