SourceTree crashes on startup

[Steve Curtis]

SourceTree is crashing on startup. I've tried unistalling, removing the folders at %localappdata%\Atlassian and then installing 1.9.6.1 again.

In the windows event log I have the following:

Application: SourceTree.exe

Framework Version: v4.0.30319

Description: The process was terminated due to an unhandled exception.

I don't have an answer for this, but deleting my Atlassian folder helped with my problem, so thanks
