      Just started my computer and clicked on my SourceTree-Icon, but SourceTree doesnot start. Looking into ProcessExplorer the SourceTree-Process exists directly without displaying any error or window. In the Logfile are some Exceptions logged, each time I start SourceTree. I don´t know what happened, cause yesterday I used SourceTree as normal.
