I've been trying to play civ 5 demo since Wednesday but to no avail. First, I believe due to my outdated laptop (3 years). I downloaded civ5 demo for 3.8GB in a hotel and could connect to steam network. Now that I try to use my new PC at home (bought about 6 months ago), I still can't play. After installing steam, I can't connect to steam. After tinkering with my router, I believe I can connect to steam network now since after launching, it is trying to update steam. Alas the update stuck at 6% for almost 1 hour now. I have win 7, geforce 275gtx and core i7 920. Hmmm... so dissapointed !!!
