After setting up everything and pressing 6 for downloading documents, I get the following:

You are using PushTAN. Please use your smartphone's Comdirect photoTAN app to validate the access request to your 'personal area'.
Please only continue once you have done so! Failure to validate this request for 5 consecutive times will result in your access being blocked.
Press ENTER after you have cleared the PushTAN challenge on your phone.

Any ideas?

You are using Python 2.7 . According to the readme, Python 3.x is required. Try an upgrade.
