I have a Pegasus R6 that works with my Macbook but won't connect to my new Alienware 15 R4 laptop.  I installed the windows driver from R_WinDrv_Installer_V6.2.0.6_WHQL.zip and the Promise Utility from R_Pegasus_Utility_200000020.zip.  I'm running Windows 10 Pro v1803.  I have an Apple Thunderbolt 2to3 adaptor.  When I plug in the device the Thunderbolt Software pops up and asks if I want to connect.  I select 'Connect Always' but then nothing happens.  I can see the device in the list of attached devices but the connection status is 'Not connected'. 

What can I do?
