I asked them for an old PDF and they said it is not available for download and sent me links to the new editions.
I have the old files on my computer, even though I purchased hard copy books. For some reason, they won't open!
Also, the new pdf course book they sent me won't open, either. The readers will open for both editions. So, it must be a technical issue, but I have tried on two of our PC's, and neither are working.
I am kicking myself so hard for recycling her old workbook. I tried so hard to pare down my school materials, and got rid of all the consumables I was "certain" I would not use for subsequent children. She is the youngest, and I have kept so many half used workbooks in the past "just in case", and I almost never used them. Plus, I thought in an "emergency", I had the pdf on my computer.
