I found that if you turn Full software control off, it seems to fix the issue, though that said that then means you can only have 1 layer off lighting and only certain effects.
I have somehow gotten mine to work now, all i have done is made sure icue is up to date, and then also check that the firmware for your ram is updated as well.
Mine was temperamental and would work, and then wouldn't work, but now seems to be working just fine.
Hope this helps you, and you can get it working all good.
