A few days ago I upgraded Sourcetree to version 3.4.5, and was shocked to discover that doing so had rendered the application useless.
When I open Sourcetree now, it does display icons with the names of my Git repositories. However, I can't open them, and thus can't use Sourcetree to do any useful work.
I would appreciate any help you can offer to enable me to use Sourcetree again.
