Silkroad help. please help me i beg you =(

[zerotolerate]

Ok, I have two computers.
First time i downloaded this game on my labtop and it worked.
But i needed to give the labtop back to someone because it wasnt mine.
So i decided to DW it on another computer.
I downloaded the offical Silkroad Site Client. It was 15 minutes or so and then there was this warning sign if i wanted to continue to other downloades to fully download. So i cliked YES. The computer just shuts down and restarts. I try it again and the same thing happens!!
Please help me I love this game so much!!
