Receiving getCharacteristics error when attempting to use LSL on Windows 10

[ghost]

I have followed all instructions to get the LSL working, but run into the following error when I type “npm start”:

[email protected] start path\to\my\muse-lsl-master
node index

Device name: Muse-B044
(node:14784) UnhandledPromiseRejectionWarning: getCharacteristics error: characteristic not found
(node:14784) UnhandledPromiseRejectionWarning: Unhandled promise rejection. This error originated either by throwing inside of an async function without a catch block, or by rejecting a promise which was not handled with .catch(). (rejection id: 2)
(node:14784) [DEP0018] DeprecationWarning: Unhandled promise rejections are deprecated. In the future, promise rejections that are not handled will terminate the Node.js process with a non-zero exit code.

The process does not terminate, but it also doesn't appear to be sending any data across the LSL either. I am using the 2016 Muse and a DG40S Wireless 4.0 Micro USB Adapter. I have tried this on both USB 2.0 and USB 3.0 ports.
