Hello SublimESmokeR, and welcome to Seven Forums.
If you would, please fill out your system specs
to help us determine better if your system may be the minimum requirements for it. Specifically, we need to know what the brand and model is for your monitor and graphics card/chip, or brand and model of your computer it it's a store bought OEM computer.
Check the items in the Warning box at the top of the tutorial to see if any those may be the issue.
In addition, do you have the latest driver
version installed for your graphics card/chip, and monitor (if one is available for the monitor)?
