What do i do when i done everything the instructions said,and mine is already enabled?

OMG, I cannot believe this, It took me 2 hrs and a bit more just to find this place where I could ask a question, fweeewf!, Help would be appreciated, my flashsplayer stopped working, and I went to try to enable it(like it said to) and mine is already enabled, and still will not work, I do not understand 99% of the computer words filters an stuff I don't get it, all I know is I done everything it said to and my computer is already enabled, I am using laptop windows 8.1, and already have the lastest flash player(that's what it said when I checked) as well, can I uninstall that one, and install the newst one again, to make it easier, I don't know what to do, I been up for days trying to figure this out. my servce providers almost "stung" me for 129.00 just to install a flah player(yours)that is already installed on my pc.  I do not usr "clouds"of no typr, do not understand it, it took me 4 yrs just to learn the little bit I do know, I do not need no more confusion added to me, I am stressed right out!, and do have a learning disabilitly, it takes me along time to learn new things, but with simply, to the point directions I can. I couldn't watch the video's cause my flashplayer don't work

Thank you kindly
