I am not a techie. Sure I love creating things for my classroom, and I really do enjoy integrating technology into my lessons, but when things don't work correctly I am lost. That's why it was so frustrating for me when my school Mac wouldn't open any of the PDFs I created on my personal PC. Almost every document would have sections of black fuzzy lines or there were portions with no text at all. It took me hours, even days, to finally find how to solve this problem (and maybe a little help from the husband after he noticed my extreme frustration with this).
I knew that I had to download the most recent version of Adobe, which is Adobe X, which you can download like any other program. It is a free program and you can download it here.
I did this, but my documents were still not showing up correctly. I remembered reading something about opening the documents with Adobe instead of preview, but to be perfectly honest I had no clue what that meant. I finally noticed that at the top left of my documents it said 'preview', so I knew that I had to find a different way to open the documents.
After A LOT of trial and error, I finally found how to open the document in Adobe rather than preview. I went to 'file' and then clicked 'open with' and selected 'Adobe Reader 10.1.0'.
It finally worked! I've been able to open any document since them, so hopefully this will help anyone else out there who has experienced the same problem!
