Windows install

I managed to get Grakn server running on the Mac but Windows is being a pain. When I run ./grakn server start I get the happy message :
PS C:\grakn-core-all-windows-1.8.4> .\grakn server start
====================================
Grakn Core

                                     THE KNOWLEDGE GRAPH
==============================

                                                                                  Version:  1.8.4
Starting Storage....SUCCESS
Starting Grakn Core Server.....SUCCESS
PS C:\grakn-core-all-windows-1.8.4>

Any ideas why this is failing? I am getting this entry in my grakn.log file about every .5 seconds, until I issue .\grakn server stop.

can anyone please help i am also getting the same error

Hi! Looks like you’re using a version of Grakn 1.8.4 or prior (the error cites janusGraph, which is no longer a component of Grakn from Grakn 2 onwards). Please try upgrading to the latest release for much improved stability and Windows support! You can find the latest release here:
