Ok I respect the technical acumen of everyone here, so here's my problem.

I upgraded my laptop to Vista Ultimate from XP. I purchased 7 and will install that when it's released.

I'm having the Blizzard Downloader problem that is mentioned in many places on the WoW Forums and the Internet in general. The difference is I'm doing everything mentioned (I think) and still can't get the downloader to work.

I've forwarded my ports. I've opened up Windows Firewall and Windows Defender. Yesterday I was home, but today I'm traveling for work and using hotel internet, and I still can't get anything to work.

Did anyone find anywhere on the Net a comprehensive guide to fix this type of problem?

Thank you.
