I have just purchased the Macbook Lite..Air. It is OK, but I am having an extreme problem. I have downloaded HOTSPOTSHIELD, and it works. But no web page will load.I have tried everything...removed my firewall,turned off private browsing,allowed every plug in and turned off stealth mode. I simply cannot get it to work. (2) Same problem with Adobe..I downloaded the program and it says that it is running, but I can only watch a few youtube programs, the others stating that I need to install the Adobe system! HELP>>>I am a novice!!!!!!!
