Hello!
When I was working, there was a power outage while Sourcetree was opened. After that when I try to open it, I see only the sourctree logo, it is dissapear after 2 sec and nothing happening after that. I tried to uninstall it, deleted all of the files from appdata which has to do with sourctree, tried older versions but nothing. I think somewhere a file is buggy, and prevent opening sourcetree, but I have no idea where or what to do now.
