Hi, I bought Pillars Of Eternity last night and left it to download. Tried to open it today and it won't even try to launch - no bouncing, nothing. I double click it, the app icon pops at me and then nothing happens? I've tried restart etc, nothing's worked. System spec:- Macbook Pro (Retina, 13-inch, Early 2015) Processor: 2.7 GHz INtel Core i5 Memory: 16GB 1867 MHz DDR3 Graphics: Intel Iris Graphics 6100 1536 MB Currently have 73.74GB free of 120.11GB. Thanks.
