I messed up my GitHub repository and just want to start over. I'd had SourceTree 1.9 installed on Win 8.1, removed it via add/remove programs, deleted by messed up repository, removed the Atlassian program data.
Downloaded SourceTree 2.1.25 and, upon install, it still shows that messed up repository. I also went through the registry, removing all references to either Atlassian or SourceTree.
What additional settings do I need to remove to start over with a fresh installation?
