Hi Jay,
Welcome to the Forum.
As I see, 1.80 Ghz for the processor is rather low as you need a minimum of 3.0 Ghz as processor clock speed.
Besides this the FX 5200 graphics card too, is way below the recommended GeForce 8800 GT for SSE.
RAM at 4GB is good since you have Win 7.
The low performance of SSE is due to these drawbacks. There is only one version of SSE and it has since been updated to Version 1.3 through patches. I quite doubt you will get a refund. System Requirements have been made very clear in the website and also on the box of the DVD. Where did you buy it from ?
