A colleague set up a repository on Bitbucket and invited me to join. I've never used Bitbucket before, but registered and was able to view the project pages and source.
I followed the link to download SourceTree (on Windows 7 Ultimate x64 SP1), went through the setup wizard, and installed the internal Git and Mercurial packages. Now I'm clicking the SourceTree link directly in the Bitbucket page, but SourceTree states ""This is not a valid source path / URL" in the clone repository dialogue. There is a "Details" button next to the message, which simply produces an empty dialogue box.
This also happens if I browse in the "Hosted Repositories" dialogue. How can the path be invalid, if it's directly produced by the Bitbucket website or the SourceTree browsing process? What do I do next?
