Ganglion Not Starting Data Stream (Windows 10 5.10 GUI, 2.0.1 Firmware)

I've got a Ganglion board I want to tinker around with, but when trying to use the OpenBCI GUI it tells me it can't start the data stream. (It's possible I need to go to BrainFlow forums to ask questions, but figured I'd try here first.)

Error message:

[DEFAULT]: openBCI_GUI: startButton was pressed. Starting data transfer, wait a few seconds.

[ERROR]: Failed to start data stream. Please check hardware. See Console Log or BrainFlow Log for more details.

Setup details and initial diagnostics/testing:
Windows 10, latest GUI (5.1.0 at time of posting), board is running latest Ganglion firmware (2.0.1)
-confirmed running software as administrator
-confirmed board is on the latest firmware
-using a Ganglion Bluetooth dongle
-GUI will detect the board and connect, but upon clicking 'Start Stream', freezes for a few seconds, then displays the above error message in the console
-installed BrainFlow with dependencies (Java) separately just to see if that would help
-read through this discussion:

What I haven't done yet but might do:
-reload the Ganglion firmware; the board is from the Kickstarter days and I managed to get it hardware-programmed for OTA updates but it's possible I goofed on that somewhere and need to reflash it - the unit shows 2.0.1 for the software revision string, so I think it should be fine

Any help would be appreciated; I'm thinking I'm missing something but not sure.
Thank you! -Vee
