Xbox live is retarded!

So I finally receive my copy of Universe at War. I was excited to play it in my home pc. So I started installing it, everything went allright. When its done, I start the game. It doesn't want to start. Instead, it froze my pc. Tried this 3 more times, even shut down my Spyware Doctor. Still failed. Then I put the game cd into another drive, and voila, it works.

In the main menu, it says theres an update for the game, I clicked no, not wanting to waste more time. But it was nice to know of this feature in the main menu. Then up comes the Xbox live prompt... sigh.

So I clicked yes, I have a Live ID and tried entering it. Then it tried to download profile. Screen freezes for a few minute. Then up comes a new prompt, asking to update Live, or else, I can't sign in. so I have no choice but forced to click yes, because I want to login so to obtain game achievements. So it tried to download an update that took a while. Then the game exit to windows and tried to run a new Live package, ending up crashing my computer!

One and half hour later, no luck signing in to Live. I can run the game fine, but can't sign in, so no achievements.

This is so ridiculous!

Updates:
Our programmer expert, Brian, told me to go download the Live package manually and removed the current version in my pc. I did and it finally worked! Still, I never had any problem with PC games before... Live for Windows has a long long way to go.
