Fatal Error on Game Launch

[b@llsdeep]

When launching the game I get the following alert:
FATAL ERROR

prog/engine2/ioSys/ziblo.cpp,92:
zlib error -5 ((null)) in inflate
source: 'ui/pages.ddsx'

This is the first time i'm launching the game and therefore cannot play, as each time I try to launch the game I get the said error.

I am running Mac OS 10.10.4 (Yosemite) on a 27 inch iMac, 2.8 GHz Intel Core i5, 4GB RAM, ATI Radeon HD 5750 1024 MB.

Any assistance as to why I'm getting this error would be appreciated.

iOS Standard Directories: Where Files Reside / Table 1-1

As of this Page tells me that Apple doesn't let the user have writing access to the files. They can once being written and then aren't writable any more. Maybe in the installation routine went something wrong. It seems you have to download it again.

Thanks. I'll try that.

I have similar specs but the game doesnt crash, but it just shows a white screen.
I can hear the sound of the logos fading in, when i move the mouse, i hear the clicking when hovering over a button, but - white screen.

What can I do?
