NSIS error for new T3D 1.1??

I am new to Torque, I should start off by saying that cuz I might just be doing something wrong. But I've tried downloading and installing T3D 1.1 three times, and every time I get the NSIS error saying it's corrupted please contact your administrator or try again. Has anyone else experienced this? Is there something I should change about the way I'm downloading it? The way I did it was I went to my products, and clicked the download link and that brought me to a page where there were 3 things to download, T3D parts 1, 2, and a DAE to DTS converter, along with the older versions of Torque. The converter downloaded just fine, its the actual program that I'm having the issues with. FYI I am using windows and for my two computers am installing it on an laptop running XP and a home computer running windows 7. I tried downloading it from both computers and neither worked.
