I own a mac laptop with 0s lion operating system. I originally downloaded Adobe Flashplayer in 2011 and have updated periodically. When I joined facebook I decided to play several apps, however my adobe is blocked and I can't figure out what is wrong. I have tried updating the software. It goes to step two and never gives me a button to go on to the next step. I have followed all the steps to download the newest version but I always get stopped at step 2 of 3. I went into my download files where Adobe requested I allow them to make some changes. I did this however, it didn't seem to make any difference. I am wondering if I should delete all Adobe files and start over.
