Installed Sage 8.9 on Windows but am a brand new user. I loaded the source file I need to interpret/run (aes.sage) but when it begins to load, I get the below. The aes.sage file is open source code, so I suspect it's fine. Is something wrong with my environment? I can't seem to find any good help files on running Sage in Windows

Directly related - I cannot find the paths below (starting with "/opt...") in my install path for sage (C:/users/meyer/.sage) It appears these are there someplace....

Is there a simple "hello world" sage script to test and see if everything's working?

??? and thanks.
