I was trying to download an archived (tar) version of my workspace. In so doing, I am afraid that I messed up my workspace environment. Now, when I try to open the Jupyter program for week 3 (C3M3), I get a load error in a big red rectangle stating something like "Load error. File does not exist. Please advise how to fix. I was just about complete with the project; hoping I do not have to start from beginning again.
Thanks, Roger
