Received my Crucial Ballistix Tactical Tracers today (BLT2KIT8G3D1608DT2TXOB). I've installed them into my system without issue. However when I try to run the M.O.D utility it is giving me the error, "invalid class".
I'm currently running Windows 8.1 Pro x64, Asus Z77-M Pro, 2 SSDs and a GTX770.
I am sorry for the issues that you have experienced with your Ballistix memory modules and the utility mod. At this point, I would recommend contacting us directly. Please use the information in my signature for region. I am sorry for the inconvenience that this may cause.
