There shouldn't really be a problem..

Hello and welcome to the Forum,

Is that a new computer, or a newly-installed graphics card? Are the card drivers up-to-date? See this here: http://www.nvidia.com/download/driverResults.aspx/120905/en-us

Also, when you go into the options menu under the graphics settings (if you even can access the options), what do the sliders look like? Are the sliders on each setting on "Low"?

Yes it had a newly installed graphic card. I clicked the link you sent me, updated everything but everything is still pink.

All the sliders are automatically put on low. Once I put them on high the game prompts me to restart it, which I do. Once I do and open the game once more, I notice that the sliders are back at low instead of high.

I've reinstalled the game and still nothing. Same issue.
