Transferring files using windows explorer

I haven’t transferred files using explorer lately, been doing it right from a memory stick but today I’m trying to transfer from my computer using windows explorer, when I click on the hub it topens a Windows Media Player window or the live hub website.  
I gather some of the recent firmware upgrades caused this?  No way to transfer from my computer now?

Never mind, did some clicking around, remapped the drive using WD Discovery…  

You shouldn’t really have to map the unit, just add it to your windows workgroup and it should show up fine in windows explorer.
