I am bewildered and I hope someone can help me.I have an Acer 7535, running windows 8, I lost the key for my disc and cannot buy another one.I tried to download Adobe flash player, I go through the whole set up, however it is not in my add and remove programs. When I am watching clips on the computer, youtube or facebook or other sites they sometimes will not play, it has the broken circle that goes around and around, also, the words are all jumbled cannot understand anything. Can someone please help me with this, thank you..
