Modules not detected / autosuggest no longer appears

Hi,

Initially I used Pycharm with Python 3.6 and liked the auto-suggest as it showed me which elements/objects were available with whatever modules I was working with.

Something has broken recently when I uninstalled Python 3.6, and installed Anaconda with Python 2.7. I created a new environment in Anaconda for my Python 2.7 install, and set the path to python in Anaconda (C:\ProgramData\Anaconda2\python.exe) as my interpreter.

I can now run a script using the Anaconda command line. But Pycharm's "run" button is unavailable to be clicked on. Most importantly, the modules all appear broken (red underlines and red flags on the right side). And auto-suggest no longer shows the various objects in these modules.

I guess Pycharm is having trouble reading the libraries in my Anaconda environment. Anyone know how to fix this?

I'm running Python 2.7.14, and conda 4.4.11 on Windows 10.

I think that my project structure settings may not be correct as they don't seem to include the conda environment (Do I need to add the conda environment as a content root?)
