The game would load, I would catch a glimpse of the login screen then the game would crash. I’m running Windows 7, so I tried the following things that have reportedly helped others;

1. ‘Running as Administrator’,

2. Deleting / Renaming the Battle.Net User Folder,

3. Opening up my firewall temporarily,

4. disabling my Anti-virus software,

5. Running a mal-ware scan (AdAware Free) and virus scan.

6. Changing my ‘Internet Options -> LAN Settings’ to not use a Proxy / use automatic settings.

After these all failed, I decided to reinstall, which made the problem worse. This time the game would state that I had to download a patch. Upon clicking ok, it would crash and restart – once again telling me to download the same patch. I didn’t see the launcher software at all, just a flash of a black screen.

Anyway, if you’ve tried all of the above and still can’t get it to work – I found a fix that works for me.

I launched IE (which I rarely use, as I use Chrome or Safari) and found that it was set to ‘Work Offline’. When I disabled this option, and tried again – StartCraft II updated and worked fine. Hope it helps someone.
