Good luck in getting to someone on the phone!
Your problem is that the 7D Mark II was not supported until Lightroom 5.7.
So you either need to purchase Lightroom 5.7 or Lightroom 6.0
Download and use the FREE Adobe DNG Converter version 9.0 to convert your RAWs to DNG, and then import the DNG into LR 4.4
Thank you so much! I will purchase LR 6
