Hi Leyinruz,
Welcome to the Forum.
Please register your copy of SS 2008 CE in your Profile in his Forum. This will allow you access to all other boards of the Forum including Tech Support. You will also be able to conduct a "search" and possibly home down on a post mentioning a similar problem
At the moment, the drawback I can see is the clock speed of your processor which is 1.83 Ghz. The System Requirements of SS 2008 recommends 2.4 Ghz. Please see attachment.
