A new patch, a new problem. If you experience the same launcher crash that I experience and want to get this latest patch, you have two options:
- restore from an earlier archive with patch 1.4x and let the game update, then start the game with SC2Switcher.exe
- reinstall (ouch!)
I'm one of those people that keep backups of important stuff so the first scenario applied to me. I will submit a ticket, you guys feel free to do the same.
