Sorry for the long delay in a reply. Please try turning off any third party firewalls or anti-virus and see if you can connect. If you can you need to open ports.
Firewall / Virus protection disabled. DMZ-plus mode for the computer in router config. Admin mode. Windows Vista, AT&T U-Verse.
When I uninstall/reinstall, the first attempt will usually get to about 11MB into the patch (gets me pumped up!) before I receive the Error: Connection Dropped. After that, it gets to "Analyzing Files..." and then I get dropped before any type of download occurs. If my firewall was blocking, wouldn't it not even get started with the first 11MB? Is there some type of log that shows my attempts on the server side which might help explain the drops?
