Data source download

I am unable to locate "details" to download the starter workbook as well as the "Non-Profit Donations South.csv" text file to proceed with the activity sections of the Analyst elearning path. Have tried accessing the learning path on both Google Chrome and Mozilla Firefox but to no avail. Clicking on the word, "details" in the pop-up as suggested by the Help video, didn't lead me to a new tab containing the data source(s)/workbook(s) to be downloaded. Appreciate any help.
