Hi All,

I am running a

Mac Pro (Early 2008)
Processor 2x 2.8 Ghz Quad-Core Intel Xeon
Memory 8 Gb 800 Mhz DDR2 FB-DIMM
Graphics NVidia Quadro FX 5600 1536 MB

Yosemite 10.10.4

I recently upgraded to the graphics card above. The game used to run ok with minimal settings on the previous graphics card, but since upgrading to the one above the game won't launch.

When I click on the icon in the task bar is bounces up and down but then nothing happens.

Any ideas?
