I'm stumped... I haven't the slightest idea why it still won't work if you've done everything that I said to do in my forum post. I will try to get Andrew Balfour, a staff member and support ninja, to help you with this issue. He probably knows a great deal more about this application than I do. However, there are just a few more things to try before that:
- Try verifying the game cache. Do this several times so as to be sure that it got all of the files (you will need to delete the "installscript.vdf" again; Steam will have put it back in that process).
- Deactivate all in-game content, like chatting and in-game notifications.
- When the CrossTie tries to install Adobe Flash Player, don't let it. It is only required to display the adds while loading the scenarios and may break it in special cases (this is a new piece of information I was not aware of before).
I don't believe that the retina display will have any effect on running the game (the game is actually built for PCs with much higher technical specifications than even our MacBook Pros).
Also, you do not have to use the Grab application to take screenshots. Simply hold Cmd+LShft+3 to take a screenshot of the entire screen and Cmd+LShft+4 to select a specific area for the screenshot. The resulting image will be saved to your desktop.
If those three suggestions do not help, let me know and I will try to get Andrew to help you.
Cheers
