[Errno 13] Permission denied --for files (PycharmEDU 4.0.2, OSX 10.11.6)

Upgraded to PycharmEDU 4.0.2
I opened my old project file via PyCharm and the files have a lock symbol on them
I am able to run the files unless I change them; then I'll get the following error

/Users/me/PycharmProjects/Introduction_to_Python/.idea/VirtualEnvironment/bin/python: can't open file '/Users/me/PycharmProjects/PyEx/test 901.py': [Errno 13] Permission denied
Process finished with exit code 2

I do have the correct permissions (via get info in finder)
How do I unlock these files? or fix this issue?
