Initially I did create a new empty project on GITHUB and then checkout to PyCharm.
After adding most of the code I did try to commit this first build to GITHUB but failed to do. When I open the Commit dialog always the same very outdated situation is displayed.
I tried every thing, but I can't open nearly any other GIT dialog. The only thing what I can do is GIT checkout and then test the connection.
So finally I used an external GIT client to commit and all works perfect. But I wonder what's wrong with PyCharm VCS.
I'm working with Version 4.5.4 on Windows 8.1.
