I have a strange problem in pycharm that I can not find about.
If I try to start the file from scratch, nothing happens, without errors. They worked fine in this version (2016.3.2), but now, if I check the launch configuration as shown below, it shows the default project as none, even though it is installed and works for project files.

If I change this to something real, a scratch will occur, but I have to do this for each file.
I think this problem has something to do with renaming the project folder. I think that I could probably solve the problem by deleting the pycharm project files and reopening the project, but maybe there is a better solution there.
