Mac error when downloading

I have downloaded Pokemon Insurgence multiple times and I still haven’t had any luck getting the program to open. On my 2012 Macbook Pro with the most recent update, PK Insurgence just says and gets stuck on verifying when attempting to open the download. It also says that there is a read error when I get past that and it still won’t open.

I’ve downloaded it to the desktop, went through the Wineskin and Winery, but still no dice. There must be something I’m doing wrong because nothing is cutting it. Can anyone help me play this awesome game? :frowning:
